<s>[INST] Two days ago, I begin experiencing extreme pain in the hip/gluteus maximus area. It s tough to sleep and walk, or even sit. I ve used a heating pad and have taking motrin in an attempt to provide relief from the pain--to no avail. The only physical thing I ve done in the past two days is get in and out of the car. What could be the problem? Also, might it be something I should get medical attention for? [/INST] Hi,You may have pulled your gluteus muscles during some strenuous hip flexion activity. So I suggest you to sleep over your stomach, don't walk too much and take rest. You may opt for in home physiotherapy sessions as in physio there are various machines like (ift, tens and heat therapy which will  give you pain relief). If it doesn't get better with 5 sessions then do visit your orthopedician.Hope I have answered your query. Let me know if I can assist you further.Regards, Dr. Harsh Swarup </s>
