I've been dealing with pain in my hamstring for about a year and a half off and on.. I am in high school, currently starting my sophomore year, and this has been a super debilitating problem. It seems to flare up right before the state meets and stuff. But it flared up in around April and since then I've been in constant pain, when running, sitting, laying down, etc. I got two prolotherapy injections so far, and I don't really notice a huge difference yet. Did anyone else have this injury and prolotherapy work for it? I'm just wondering how long it will take. I really want to run in college and I just want this pain to go away so I can enjoy running again and be as fast as I used to be. Plsss help
