Ouch!!

It’s currently 2:30am and I’m stuck wide awake with extreme pain in my lower calf. It’s not so much a throbbing pain but it feels as if you would imagine how someone would take their hand and just squeeze all of your muscles and pull them. Its not cramps either. I’ve taken Advil and tried sitting in a warm bath which helped a bit but the pain is back and won’t go away. I’m not sure what else to try. Any ideas?
