i woke up last friday with extreme pain between my lower back through my thighs and stinging down on leg. I could not move for about 3 days. 5 days later, I m feeling much better. However, I cannot walk without being hunched over, when I sneeze or cough I can feel it in my gut, my right leg has a stinging feeling and very weak compared to other leg. My lower back is very tight feeling. Also, muscle in buttocks feel strained
