Wrist pain. What could be the problem?

This pain started after I got influenza in the 25th of Dec/2016 during my influenza my wrist and right hand started to hurt mildly I thought that after my sickness the pain would go away but it didn't so during this 3 months it started to get worse the pain. I went to a neurologist doctor who prescribed me Arcoxia and a steroid medication for a week during that medication the pain went away but you could still that it wasnt the same if you overextend my left wrist it has some pain feeling so after that medication maybe in 3 days it came back and worse after 1 week I took the medication again without the doctor's prescription after that 1 week my left wrist pain went away but my right hand came back so in about 2 weeks the left wrist pain came back it's today and my right hand's pain when you twist it is mildly disappearing what could be the problem? thank you for your time
