Hi! Good evening. I am Dr Shareef answering your query. There must have been a hematoma over the trauma site which has started organising now becoming a firm not and with reduced inflammatory signs. If I were your doctor, I would advise you not to fiddle with it, and prescribe you with an anti inflammtory , a serrato peptidase, along with a proton pump inhibitor which would give both symptomatic relief, and would also cause it to reduce gradually. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
