<s>[INST] I swong a golf club way too hard and hurt my lower left side of my back. I was able to finish my game but in the morning, besides just my lower back ache I had a burning sensation in my upper left thigh with very sensitive skin to the touch. It still bothers me after almost a week and sometimes it migrates further down my leg.Usually it is the tenderness that bothers me the most then an aching pain, but sometimes I get a sharp pain in the upper left thigh.
