<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a bad back, so I need a firm mattress. But sleeping on it causes fairly severe pain in all the pressure points ribs, shoulders, hips, back. I tried putting a softer mattress pad on top, but then it doesnt support my back properly. This has been a problem for years, and appears to be growing worse as I get older now 56. What would cause such severe sensitivity to pressure andor what kind of doctor should I see about the problem? Thank you.  <response>: Hi, According to me, you should consult musculoskeletal and rheumatologist both. Because you have a chronic problem, so the cause should be found if it is muscular, a bony problem like osteoporosis or related to joints like Rheumatoid arthritis or Ankylosing spondylitis. You need to get X-Ray Blood investigation and proper history to know. Hope I have answered your query. Let me know if I can assist you further.
