Hi I pulled my hamstring really bad. It hurts when I strech my leg out, when I twist to fast, when I cought or sneez, and when I stand up in takes a few moments before I can straiten my leg and walk and it sometimes hurts while walking. It's been hurting for about 2 weeks. I have 3 questions. 1.) does that sound like a pulled hamstring. 2.) any tips on what to do? 3.) Im taking ivprophan but I'm scared if I take it any longer my liver will fail and il get really sick. Thank you for your help.
