<s>[INST] When I roll over sometimes in bed, I get a pain in my upper inner thigh--almost as if some muscles are crossing each other and snapping. I have excruciating pain for a few minutes and then it goes away. It s been happening more frequently. What is happening? [/INST] Hello, It is just a musculoskeletal pain only. As of now take adequate bed rest and analgesics like tramadol can be tried. Apply icepacks for faster recovery. Generally, the symptoms will settle in a couple of days. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shinas Hussain, General & Family Physician </s>
