### input:
Over the last couple of weeks I have been in an awful lot of pain in my back (lower left hand side) it doesnt hurt so much when I stand and walk but always when im sitting. It shootsthrough my back, down my right buttock and into the top of my thigh. It just seems to be getting worse and it s affecting my job. I am currently on co-codomol tablets for pain from endometriosis and PCOS. I was wondering if they are related or if there may be a different problem?

Hello, Welcome to Chat Doctor. Thanks for writing. I am Chat Doctor.  I have read your question completely, I understand your concern and will try to help you in the best way possible. I am sorry to know about the problem you have been facing, Your pain does not seem to be related to endometriosis or PCs, it is quite a characteristic pain which happens in nerve impingement due to muscle spasm or spine issues.That's why when there is pressure on the nerve while you sit, the pain shoots down along the nerve pathway all to way to your thigh. There are certain measures which you can take for it some will benefit in short term and some will benefit in long term.1) Take Rest and avoiding sitting when you can.2) Warm compresses, warm water bottle under this area will help to relieve muscle spasm and will loosen up inflamed tissues.3) Rubbing ventral gel over the area can be helpful.4) You may be suffering from low bone density because of low calcium and vitamin D due to your hormonal imbalances I will suggest you to take vitamin D and calcium supplements 1 tab daily.5) You can take Cent rum for women daily one tablet. I would also suggest similar patients in my clinic to take muscle relaxant like Move 4 mg twice a day this really helps. You are already taking a heavy painkiller, so I would not suggest you to increase the dose.If this doesn't settle in a week or so, Get a check-up by Neurotypical surgeon he might want to get your X-ray lumber spine done, or you MRI spine, this will make causes and treatment options clearer to you and your doctor. Hopefully things will settle down soon. I hope this answered your question. If you have more queries I am happy to answer.Otherwise, rate and close the discussionRegrads.
