Hi,Dear, Thanks for the query to HCM.I studied your problem in depth and I understood your concerns. Treatment for the painful lump on the lower back- In my opinion your-pain in lower back-was fixed by your doctor as Swelling? which is mostly due to the prolapsed inter-vertebral disc. and not due to any obvious swelling as thought by your husband or by your chiropractor. Dont waste time on wrong treatments. MRI- now done would resolve the issue. Hence you should investigate it with your ER Ortho-Surgeon,who would treat it according to its cause. From your facts of the query-In my opinion-your constant pain is due to the improper treatment of the ?-Spinal Canal Stenosis,which you seems to suffer from.This could be confirmed by MRI and would also remove any doubts of lump in the lower-back you and your doctor has.This stenosis if present could be decompressed by endoscopic laminectomy or facetectomy instead of the open laminectomies and could be done with almost no post-surgical instability and morbidity post-decompressions. So take treatment from your ER Ortho-Surgeon, who would treat it after due investigations and 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.
