Hi,Dear, Thanks for the query to HCM.I studied your problem in depth and I understood your concerns. Treatment / Cause for the lumps on the palm-In my opinion your description needs more clarification-as to -whether the lump is on the back side of the hand or the front side of your hand? This is because your lump is under the main vein/ and the veins are on the back of the hand and not on the front or the palm of the hand. In my opinion-your lump is -Ganglion of the left hand -a working hand. -Consult ER-Surgeon. -Take Anti-inflammatory tabs / hot fomentation / and rest to the part for 3 wks atleast, which would relieve you. Besides this being a continuous disease-I would advise ER-Ortho-Surgeon follow-up and treatment. If no relief-Endoscopic Laser Ablation of the Wrist Ganglion-may be needed. and hence needs ER Ortho-Surgeon check up and needful treatment. If not treated it could increase your leg pains and bruise constantly. So do check it up from ER Ortho- Surgeon. For Final Diagnosis and treatment needs clinical data from a Doctor. and Hence for further treatment I would advise you to Consult ER Ortho-Surgeon , who would treat it accordingly. This advise is based on the facts from the history you give and needs further clinical check. Hence I would advise you to check with ER Ortho- Surgeon. So don t build up wrong concepts and create more psychic complications in you which would increase risks and costs to you. Hope this would relieve your problem. Welcome for any more query in this regard to HCM. Write good resume and Click thanks if you feel satisfied with my advise. Have a Good Day. Dr.Savaskar M.N.
