Hello, Two weeks ago I had discomfort in my lower back. Ice/heat helped but about a week ago a was lifting about 30 pounds and had acute pain. Pain continued for about 72 hrs, and went to about a level 8 on a pain scale. I am now experiencing a heaviness in the leg, can t lift my knee up to my chest, and it feels like the leg may give out as I walk. I no longer have pain. Should I just wait and see what happens, or should I be seen? Rebecca
