Hi i am Dr Ahmed Aly thanks for using healthcaremagic site , I had gone through your question and understand your concerns .. In my opinion i think your husband may have a sort of arthritis in his hip joint that may have exaggerated his old sciatica problem . Arthritis is a type of inflammation that happens within the joint causing swelling and making more pressure on his spinal nerve roots and increasing his pain . For my patients i may recommend Advil tab when needed , hot massages with topical gels , B12 vitamin supplementation , avoid standing for a long time and over using his joint , vigorous movements with some elevation of his legs , healthy life style and low salt and proteins meals will be effective for most of cases . If his pain persists i recommend a visit to his physician for proper evaluation and management . Please click and consider a 5 star rating with some positive feedback if the information was helpful. Wish you good health, Any further clarifications feel free to ask.
