Have you taken any opinions till now? Has any doctor examined you? 5 months is too long time. Can you exactly tell which part of wrist is painful. Can you post photos of wrist with marking.

Pain in wrist can be due to many reasons. However one condition is seen predominantly where some muscle tendons around the wrist become swollen and give rise to pain, its referred to as DeQuervans tenosynovitis. I suggest you get it examined by a orthopaedician first. Get it diagnosed. DeQuervans is completely curable if treated properly.
