<s>[INST] I have chronic pain and have received several trigger point injections on both sides of the upper shoukdet. Additionally i am having almost constant tingling/numbness from my lower back down both legs but primarily the right side. I also can be walking along and then get severe pain in the hip/buttock area which stops me in my tracks. If I wait a couple of minutes it goes away. This has been occurring in and off for several (6) years. [/INST] Hi, This back pain is likely to be Lumbosacral radiculopathy due to nerve root compression and canal stenosis. Get examined by a Neurologist and get a MRI of lumbar spine too. Hope I have answered your query. Let me know if I can assist you further. </s>
