Can I get some experiences from other people please? I have been playing tennis for about three months now and I have to say I am having a blast. But there is now a lump on my lower arm. Judging by the timing of its appearance, it has to be related to my sporting activities. What can I do to get rid of this?
You are probably not going to like the sound of this, but I am guessing that it is related to the tennis indeed, and that the only way you are going to get rid of it is to quite tennis for a while at least. You should probably visit a doctor to be sure, but I guess the lump was caused by repetitive movements.
