“ I feel your pain, literally”! LOL! I have had the same pain going on about six months. I have pinched nerves in my lumbar and have had steroid injections and Radiofrequency Ablations for that which didn’t work. I didn’t have the sit pain while sitting until after the ablations but I had gone to a chiropractor and he taught me some deep stretching exercises and I think the deep stretching may have torn something . We did do a repeat MRI after returning to the Pain Dr., but I haven’t had my follow up and I think the not so bright Dr just did the MRI of the lumber again because the report which I can see didn’t say anything about my ischial tuberosities. I did tell her I have pain sitting. MRI did say I have severe facet arthropathy/ arthritis. I see the pain Dr next week. All said you mentioned doing a steroid injection in that area, so did my Dr but I have had 4 in the last six months and my HgA1C and triglycerides went up. Will your insurance pay for RPR????? Most don’t. I do different supplements for inflammation, I can’t take Pregabalin because I have severe colon inertia and the Celebrex that I asked for irritated my stomach so I stopped. I’ve helps! I’m tempted to spend thousands out of pocket which is what it cost for RPR so I can sit . I work a desk job so it’s hard and we also make a 750 mile car trips to see my daughter every 4 months. It’s a miserable life not being able to sit. I stand a lot so that hurts my back more. I have every kind of cushion on the market and have made home made ones with wholes to take the pressure off but they work about 50%. I’ll be stuck with another MRI bill too. Drs today don’t impress me. That is why this site is good because your Dr may be better than mine and are better diagnostician's . I don’t have a problem telling a Dr what I need and of my health concerns. How do you think you tore your hamstring?
