Hi. Thanks for your query. Noted the history and understood the concerns. As per the history, you have a lump at the inner aspect of elbow and also have tingling and numbness at the forearm and hand. This indicates that the lump is pressing on the Ulnar nerve causing you hte symptoms. I would advise you the following: Consult a General Surgeon and/or an Orthopedic Surgeon for clinical evaluation and examination, nerve conduction study, MRI of the affected area to see whether this lump is something different than the nerve or a part of the nerve. Once confirmed further management can be done easily. Getting the proper diagnosis is the key to the proper treatment. Till then continue exercises of the affected part by active exercises so that the power is not lost totally. Take multivitamins and nerve tonics under Doctor s prescription.
