<s>[INST] I hope. I have been having pain hip, not my groin area, but underneath my body, on the left side. It feels like it s below my hip joint (mom had 2 hip replacements), but it is affecting my gait, sometimes feels weak, like it won t support me. I ve been walking 30 minutes nearly everyday for a year to improve my health. Am wondering about a stress type fracture or what this could be. Thanks. [/INST] Unlikely for stress fracture at this area.An xray or MRI of the region could give clue.consult hip surgeon.Try Motrin tabs,hot fomenting and use walking stick in opposite arm to lessen weight bearing on affected side. </s>
