<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I have a tiny bump on the fleshy part just below the outside of my ankle bone. It has been really itchy for about 1 year now, not anymore though and in the last couple of weeks I m getting a tingly, achy, strange feeling when I stretch my ankle, as if something is about to snap. Any ideas??  <response>: Hi, Dear thanks for the query to Chat Doctor virtual clinic. I studied your query in full details updated from you. I understood your health concerns. Based on your query data, In my opinion You seem to have Ganglion lump which snaps when stretching your ankle. Itchtinglystrange feeling is due to Ganglion Cyst only. X-ry of Anne and CT study would confirm its origin from Synovial joint or tendon sheaths. Treatment-Endoscopic Laser Ablation of Synovial Histiocytoma-a hamaromatous swelling would resolve this issue forever. No medications would help it, as its chronic. Other causes-could be bursitis on anterior ankle or synovial granuloma, which needs to be ruled out in your case. Hope this would resolve your query and worry. Welcome for any further query in this regard to ME. I would love to help you outwriting for any further query. Wish you fast recovery from this intriguing health problem. Have a Good Day.
