HI,Welcome with your query to HCM.
Based on the facts of your query,the cause of the recurring pinch with lump lately needs further clinical evaluation from your Surgeon by a
Second Opinion,who would physically testify the cause of the lump in your case, as X-ry and USG is inconclusive.
In my opinion you seems to be having -Costo-
chondritis and needs to talk with your doctor and get it ruled out.
Hope you got the answer for your query.
Hope this would help you.
Welcome for any further query in this regard
Will appreciate writing your feedback review comments,to help the needy patients like you at HCM.
Good Day!!
Dr.Savaskar,
Senior Surgical Specialist
