I studied all details of your query. I understood your health concerns about causes of shin /ankle lumps-Based on facts of your query, it seems that-you have recurring multiple Varicose Ulcers, as they burn more when you stand. When they heal up, present as bumps/bruises. The tingling is due to the rural neuropathy from inflammation. Hope this reply would help you in resolving this complex query and anxiety with it. Will appreciate your hitting thanks and writing excellent review comments to help needy visiting patients at Chat Doctor like you. Welcome for any further query in this regard. Good Day!!
