Hey all, just turned 21 last week and so far 2015 has been completely void of decent sleep due to sciatica in my left leg. It started as a very mild pain when I coughed too much (like when I had the flu) or contained sneeze, then would occasionally get worse especially with treadmill running and since January really I have not been able to sleep for more than 1-3 hours in a period without waking up to a super tense left leg and mild sciatica. I'm confused as to whats happening, my physio who I've been seeing since January thinks its SI joint pain, facet joint (which he admitted recently has basically cleared up) or something else such as muscle pain or a herniated disc. I just want to know if anybody has felt the same sort of pain as I do, what exactly could this be, how long do I have this??
