I have a dull aching pain down my left leg only. It has been hurting for over 3 weeks since when I slipped on the ice when walking the dog, but did not fall. However, I did feel like I may have injured my glute in my left buttocks. The pain comes and goes, but usually is worse when I am sitting down, driving the car or lying in bed. Walking usually makes it feel better. I also sometimes experience muscle twitching in the thigh as well as a dull pain in the lower left buttocks. Ibuprofen, aspirin and even naproxen don't seem to dull the pain.
