I'm 25 years old and i play rugby. Over the past couple of years i've racked up a fair few injurys playing rugby - Ligaments in my left ankle, Ligaments in the back of my left knee, Dislocated left shoulder, back spasms and now have mild sciatica in my left bum cheek. (which i think has something to do with my back spasm,anyways). Although i have had all these injurys it has not stopped me playing and now when i am training etc When training after a run or tackle sometimes i'll get a sharp stabbing pain in my perinium area which is excruciating. Afterwards i find it very difficult to walk/run and climbing into bed is not so easy. This has been going on for a few months now. I haven't had any problems with passing urine but i do get bladder pains now and again. Is there anything i can do to relive the pain like stretching/excerises?
