... He told me that I just got muscle strain from muscle overuse and that it's normal for the pain to be there for 2-3 weeks... Anyway, he just gave me 2 medicines, Myonal for relaxation of tight muscles and Mecobalamin for the restoration of possible injured nerves...
'tis great that you learned that you sustained an overuse injury. However, did you figure out what specific actions or reasons for the strain/injury? Is it related to the radial/ulnar deviation that I suggested? It could be, in part, due to some of your stroke mechanics. If you do not rectify the root causes for your overuse injury, you may very well see the problem again in the future.
Sir Shankalot provided some great feedback in post #9. Technique and equipment can both be contributing factors. If you are currently using poly strings, you might want to get rid of them and opt for a softer, kinder string. Or you could do as
SS has done and string with poly at an ultra-low tension (below 40 or 45 lbs). Your frame may also be a contributing factor if it is delivering too much frame shock to your arm.
BTW, did your doc indicate if
Mecobalamin is superior to other forms of vitamin
b12?

Wrong equipment: At the time of the injury I was using a rather stiff racquet (RA 67) strung at 65. This was not in itself a cause of the injury, but coupled with poor technique it certainly didn't help.
Anyways, that was all 3 years ago. In hindsight the injury was probably the best thing that could happen to me, tennis wise. When I finally started playing again I was forced to re-learn my technique, and the key fundamental I implemented was to keep my arm the same shape throughout the swing and let all the power come from legs, hips and torso. I also got myself a new racquet, a Dunlop Bio 200 (RA 57) ...
Great feedback overall in post #9. However, stiffness ratings (RA numbers) are not really the best metric for determining how friendly a given frame may be to your elbow, shoulder or wrist. Stiffness ratings be one factor in how much shock a frame might generate but it really does not tell you
how much shock is actually
delivered to the arm (shoulder, elbow, etc). Other factors can contribute to frame shock experienced by the arm. The weight or weigh distribution may be a factor.
Many rackets will often provide some isolation of countermeasure in the throat or the handle that will minimize how much shock is delivered to the arm. Cortex (in Babolat rackets) is one system that has
not done a very good job of this in the past. Don't know if the current Cortex version does a better job of this.
OTOH, the dual-dampening system used in the
Volkl V1 Classic is one of the best. Note that the V1 Classic has a very high RA (stiffness) rating of 69 (according to TW and other sources) and yet is, possibly, the most arm-friendly frame on the market. In contrast, a number of TW users have indicated that some frames with low RA/stiffness ratings (below 57) have not been arm-friendly at all. I tend to ignore stiffness/flex ratings because of these apparent anomalies.
