<s>[INST] I am having lower back pain more frequently the last year. I have had numbness in my right thigh for years. But now when the pain occurs, I am having sharp needle like pains in my right thigh. I am also waking up at night with numbness and tingling in my arm on whatever side I am sleeping on. I am a 49yr old male. First, could these separate issues be related and could it simply be a pinched nerve. [/INST] Hi, Thanks for your query. After going through your query I came to know that you are suffering from backache with sciatica. It can be due to prolapsed disc.However, slip disc is confirmed by MRI of spine. Your second problem is waking up at night with numbness and tingling in your arm. It seems to me simply a pinched nerve. Both the problem are separate. You can discuss with your treating Doctor about it. I do hope that you have found something helpful. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care. </s>
