<s>[INST] I have had twitching in my right hand near my little finger for a couple of days now my thumb is bruised a funny colour what could be wrong I have not been having any pain but one doctor suggested I take naproxen I think ibrpophen would have been better. [/INST] Thanks for posting you query to Chat Doctor .did you develop bruise after any injury, or it develops itself. As there is no pain and swelling so possibilities of infection is rare, it could be due to some injury or allergy. Non infected bruise usually heal without treatment in 10-14 days but if you are having pain or swelling you can take any anti-inflammatory medication. Naproxan and ibuprofen both are this kind of Chat Doctor. Hope you would be satisfied with my answer.  Feel free to communicate if any query.regards, </s>
