Hi Thanks for posting your query on HCM Chronic right lower back pain could be caused by many medical conditions some of which are: osteoarthritis, with lumber disc herniation or degenerative disc disease, sprain/strain and infectious causes less likely. Given the chronic nature, you may need tests like a hip/lower back X-ray, or MRI to identify the exact cause.Treatment options for lower right back pain may include : pain medications like ibuprofen, myorelexants like miorel, steroid shots and physiotherapy.Some lifestyle/home remedies that may help you get over your pain include: regular exercise, maintain a good weight, use heat or cold packs to manage pain and topical pain medications.I will suggest you see a Rheumatologist if all these options and home remedies do not relieve you. Hope my answer will help you Best regards
