<s>[INST] I think I pulled a groin muscle in my left leg. It actually started hurting in my left lower back in the night, by the next afternoon it was hurting on the inside of my upper left leg and now my left ankle and the top of my foot hurts and is a little swollen. My leg is soar and burns and is actually a little red in the groin area right above my knee. [/INST] you may have had a fall which is not mentioned here. Amy history of past falls or injury. your age is also a factor to be considered if any degenerative factor is there. kindly visit a close by specialist and get yourself checked. it will definitely help u get rid of pain and swelling. </s>
