I've had a bit of tennis elbow in the past, nothing serious, and I would usually stop for a week or two and I would have a clean slate. In fact, I had tennis elbow because I kept framing and never hit the sweetspot while serving. Anyway, that problem is long gone. I was re-demoing the Liquidmetal Prestige Mid (love that stick) and then I started serving. The thing is that I have been trying to rediscover my serve and I finally found it and it was great. So I start serving and smacking the balls like crazy and cheering saying my serve's back, finally, yayyyy. Ok, anyway, after about maybe 20 serves in a row I start to get a pain on the inside part of my right forearm. I'm pretty sure it's not tennis elbow (in this case, it could only be golfer's since it is in the inside of the arm), because lm prestige is very flexible, I was hitting the sweetspot a lot, and the lm prestige is rather heavy, about 12.5 ounces with overgrip and shock absorber. So, I got a pain below the point of my elbow and I really think it's just because my forearm is not strong enough. So, I have three questions. First, is this tennis elbow or something hazordous to my arm? Second, is there something wrong with my service motion if it led to this problem or was I just getting tired? and finally, does anyone know any exercises to help strengthen the forearm? Thank you.
