Calcific Tendonitis (shoulder)

Ryebread

Hall of Fame
Shoulder was very sore after a couple days of unusually intense matches. I shut myself down for three weeks. It was not enough so I went in for an x-ray and they found a calcium deposit on my rotator cuff. They used a needle to suck it out, ultrasound guided. Then at the same time, cortizone shot.

I’m wondering if anyone else here would like to share information.

I’m curious if it’s something that stems from plain on “playing x amount of time”, or playing too much in one stretch, or something else, vs. the possibility of using certain rackets and or strings.

I have never had any issues with my elbow or shoulder in my life. Very fit.

I have other questions, but let’s start there and see if we can get some dialogue going.

Happy New Year

Intensive overuse will spur your body to try and reinforce the areas under stress. That’s my hypothesis.
got it, thank you.
based on your theory,
when I come back,

there is no need to go away from a soft co poly at 51/48lbs,
when being used on an RA 64 stick?

I was thinking about switching to a blade or gravity after this ordeal.

my doctor told me to take 2 weeks off, then just hit on a wall.
I told him that I'll prob elect to take additional time off, b/c I don't hit casually, not fun for me....
so he said good idea, take 3-4 weeks off after the procedure.
 
Probably no drastic change needed. Could be trying to hit a heavier ball and leading a little with shoulder. I would trial dropping tension 2-3# on next string job and see what happens. You string so shouldn’t be an issue.
 
Fast toward to today.

I have been playing since the last week of January. No issues playing. A bit of general soreness at home. I don’t sleep on that shoulder these days. I had a follow up today with an x-ray. This was scheduled bc I was just nervous and wanted to make sure. Doctor said I was ok to do whatever I wanted. The X-ray showed zero calcium deposit.

The little bit of soreness was likely a result of the procedure.

I had exactly this problem for which I had to undergo surgery 15-20 years ago.

This condition doesn't just happen overnight.
The explanation I got back then from the surgeon...

Overuse / overload of the shoulder muscles (in tennis, it typically concerns the supraspinatus) causes inflammation of the tendon. The inflammation causes it to enlarge a bit. In the rotator cuff, this tendon already has just a small space where it moves through. As a reaction to this inflammation, your body will attempt to heal it by releasing extra proteins. These proteins will cause calcium to "clump up" and these might / will settle on the bone, resulting in calcification. This will narrow the space of the tendon even further, causing it to rub against it and get irritated even more, causing more inflammation. Body responds with more proteins and thus more calcium clumping and more calcification on the bone resulting in even less space for the tendon, causing more inflammation etc etc etc... A nasty vicious circle....

I wasn't playing tennis any more by that time and thus it was brewing "beneath the surface" for quite some time, which resulted in surgery being the only real option moving forward.
It did however damage my tendon quite a lot and it's become a "weak spot" making my tendonitis a bit chronic. It flares up every once in a while to more problematic levels and since I got back into tennis, the pain never actually goes away 100%.
On a "cold" shoulder, I always have that little bit of soreness / stiffness / irritation. Regular exercise, a good disciplined warm-up before playing and a cool-down after playing are absolute musts for me. I feel nothing during play, when the shoulder is warm.

When playing epic 3-setters, my kick serve starts to become problematic due to fatigue in the shoulder also. I'll start having problems throwing my arm up to give it that kick, losing a lot of power.

It is what it is.

I can only do regular work outs hoping to strengthen it as much as possible so as to keep it under control, but there's pretty much irreparable damage there so chances are very slim that I'll ever get it to 100%.


I can only advice to be careful and always seek medical help asap when soreness persists for more then a few days.
Had I not stopped playing, the problem would have surfaced sooner and likely I would have been better of today as a result.

I already had problems with supraspinatus tendonitis by the end of my first tennis career. Pain went away when I stopped playing, but the inflammation was still there and then the calcification started "in the background". Then one day I woke up in my mid-20s and felt the same kind of pain I had at 17, only this time without serving for hours before that.

Thank you for sharing.

What sort of surgery did you have
 
I don't remember what they called it exactly.

It's a keyhole surgery where they "scrape" the calcium deposit from the bone and suck it out.
Recovery period is generally 6 to 12 weeks and involves quite some physio and workout.

The shoulder comes out of it VERY weakened. I was barely able to lift a bottle of water. And not due to pain, just sheer weakness.

The best cure here is "prevention".
Strengthen all rotator cuff shoulder muscles, the supraspinatus in particular.


A good test to see if, when in pain, it indeed concerns the supraspinatus, is to stretch your arm out in front with your thumb pointing down and thus palm of your hand pointing outwards.
Then ask someone to put a bit of pressure on the arm trying to push it down and try to resist it. A weakened / inflamed supraspinatus tendon will cause instant pain when trying to resist that pressure.

I did that in early January. Ultrasound guided needle, vacuum cleaner.

In surgeon told me to take three weeks off and then start hitting against the wall if I want. I told him that I don’t like hitting against the wall- that I would take four weeks off. I did that. Been playing a couple months now.

Playing feels good.

Odd occasional soreness. Got an X-ray last week and it’s clear. Prob need to strengthen it further.
 
I had frozen shoulder earlier this year. Perhaps the most intense pain I have ever experienced. Cortisone shot followed by twice a week PT sessions for a month broke it up. Hope that never returns!! For months it felt like I had a mild tear deep in the delt and then came the explosion of pain. Moral of the story - persistent pain should not be ignored.

I could only start up rehab after 2 weeks. Walked around with my arm in suspension for 10 days or so, drugged out on pain killers

How is your shoulder holding up? Any setbacks after the treatment? How quickly did you go back to playing your best tennis?

I'm having the same procedure done in a few weeks time after having a very sensitive shoulder for around 4 years (Calcific tendonitis 12mm calcium deposit + bursitis)

I've managed to get by over the years but I want to solve the problem for good.

My doc suggests not serving + rehab for up to 6 months after having it done for the best results. That seems a very long time, but I'm willing to do whatever it takes.

4 to 5 weeks and I was back at it.

No issues, it’s about a year later
But it was feeling weird, anything over my head, for a few months. Gradually that all goes away.

I warm it up now, with hyperice shoulder thingy. And ice after - when I can.

Good luck

Just had my op done yesterday.

They got most of the calcification out but were unable to remove some of it. Hopefully that isn't an issue down the line.

My range of motion on day 2 is none existent. I can't lift my shoulder more than a few inches without a lot of pain. It's not too bad when im not moving.

I hope to see some improvement by this time next week.

Edit: My mobility is much better on day 3. Its still sore but I can now lift up my arm.

Edit: (5 weeks post op): unfortunately my pain hasn't been resolved by the 5 week mark. It pretty much feels as it did before having the procedure done.

Edit: (8 weeks post op) My shoulder has remaining feeling like it did pre-op with rest and PT. I'm getting some more scans done to reassess.

Unfortunately my procedure hasn't been successful.

I had it done on the 17th Feb and the pain is worse than pre-op as of 7th May.

I've had new scans done and the calcification has gone, but I've still got Bursitis and tendonitis.

It felt like the steroid shot wore off at the 8 week mark and my pain has only increased since then.

I'm doing PT but I'm not seeing any improvement.

At this point I REALLY regret having it done.
 
Just writing again as an update.

I've now been seeing a shoulder specialist PT for 2 months. I've seen an improvement in my shoulder but I'm still nowhere near playing tennis again.

Who knew a routine proceedure would have me sidelined for so long...

I think I'll be lucky for a 2027 return :(

Dang I'm sorry that sucks. Shoulder issues and the associated rehab are tough and as much mentally draining as physical. I spent all of 2025 dealing with what I thought was a biceps tendon issue (MRI said no structural issues, only inflammation). After exhausting every avenue I could, I went in for surgery to either clean it up or have a tenotomy and move it out of the joint. I woke up to the surgeon telling me my biceps tendon was inflamed but structurally great but my rotator cuff was toast and was repaired instead.

Fast forward 7.5 months to now and I just started lightly serving again a few weeks ago. I am back to being competitive off the ground with all my 5.0 hitting partners but serving is another matter :-D. I do at home PT 2x a day and go to the office 1x every other week. Its improved a lot but I still have residual pain in the same anterior biceps tendon spot that is driving me nuts. Seems like a fair amount of reports that it can get irritated by surgery and stay enlarged and uncomfortable. Shoulders just suck. Hang in there, keep doing the work and hopefully you'll get back on court!!

Thanks for the encouragement! Your injury sounds nasty too.

I mainly had supraspinatus tendonitis for many years, but I was able to manage it, and at points had very little pain.

Like you said, it seems like the proceedure re-inflamed my tendon and also gave me Bursitis.

I play 4.5 and I'm missing tennis a lot.

Good luck with your recovery :)
