Thumb Joint Pain Griping too tight?
I just started playing tennis and got into it very heavily (playing 4-5 hours a day). I had to stop though because I got a pain in the thumb and it's lower joint, it hurts the most when I serve. However it hurts when I grip the racquet also. If I right hand so my knuckles are in front of my face and my move my thumb directly to the left if feels as if is popping. I hope this is not serious. I think this may because by me griping the racquet incorrectly or too tight, or using an incorrect grip size. Anyone experience something similar to this before?
Thank you very much,
I've had sharp pain in my back
For the past two weeks, I've had sharp pain in my back and in my chest (below my left breast). The pain in my back is a mild stabbing pain, and the pain in my chest is a mild deep crushing-like pain that hurts mainly when I take a deep breath. The back pain is more constant but also worsens when I take a deep breath. Have you got any ideas what it could be?
