Hey guys! I took up running a while back in the hope that it would strengthen my legs ( i suffer from a mild limp due to cerebral palsy). However since iv been running regularly my limp has become more pronounced. Ive got groin pain too, its not unbareable but its been nagging my for a month or so now. My leg is becoming really stiff too. Before i started running i had none of these symptoms. It is possible that hip arthiritis has been an underlying problem waiting to come out once i started exercise that would work the hip?
