<s>[INST] I am having severe pain in my right buttocks when walking and/or sitting. The pain is a grabbing pain and literally makes me freeze in position and almost takes my breath away. It only lasts a few seconds but leaves me with lower back pain. It almost feels like something is slipping in my hip or buttocks area. [/INST] Hi Hope this message finds you in good health.I have gone through your complaints and understand your concern.U seem to have compressed a nerve in the back somewhere that might be causing radiating pain in those regions.Possibility of a lumbar disc prolapse  should be kept in mind.I suggest you get an Xray as well as an MRI to find out the exact cause.Physiotherapy,analgesics,anti-inflammatory drugs,lumbar traction ,infra red therapy should help.in difficult cases,using a lumbosacral belt should be helpful.Avoid surgery as far as possible.If at all its needed,get it done endoscopically.Nothing to worry about.     I hope your question has been answered.If you have any follow-up queries,feel free to consult me anytime.Thanks,Take care,God bless. </s>
