i need advice on what may be causing stiffnes in the groin area i am a cleaner female aged 26 and for about 6 weeks now i have had a sore groin it started off on the left side only at night after my 10 hour shift i went to move off the couch and it was sore and i couldnt walk properly it hurts to move around in bed , it is now on both sides of the groin and hurts even when i bend my knees and get back up , it comes and goes its like im going to sease or something then once im up and moving its fine another symptom is the tops of my knees feel heavy now and again i dont have time to get to the docs as i work 10 hours 5 days could this be serious ?
