I have a question about something which has been really concerning me recently.
I am 33 and a musician (piano mainly), and recently I have noticed a feeling of tightness in the middle finger of my left hand. It is very fleeting and only lasts for seconds, and there is no pain whatsoever. It feels like someone has grabbed the knuckle briefly. It happens sometimes when I play, and sometimes during day to day stuff, or if I pick something up or grab something. Ive noticed it on and off for a couple of years but I'm starting to get concerned about it now.
Does this sound like a symptom of arthritis, or something else? Maybe muscular?
I've had tests for arthritis on the past but the tests came back negative. This was because I have a grating sensation between all my joints.
I get really paranoid about not being able to play anymore, and would really appreciate some advice on this.
