Groin pain for 16 weeks. Straight after 10k run

Hey guys n gals,

Age 37 Male. 5ft 8 76kg

I have had this issue since a run on 20/6/12 over 16 weeks ago. Basically I ran the Manchester 10k in 50.21 (which was quick for me) and was so jiffed off at not getting the sub 50 that I booked the Woolston 10k two weeks later on 20/6/12.

I knew I had a very slight strain before I started the second race but ran my socks off and finished in 48.30.... That's where the issue started. The race was fine, I noticed a little bit of pain but carried on with adrenalin. After I finished I could hardly walk back to the car and was in some pretty severe pain. For nearly a whole week it was painful walking but like other injuries I just thought "bad groin strain 6 weeks off, go back really gentle and I'll be fine"

I've tried to go back 3 times with swimming, gentle jog etc and I've still got an irritation, it's not painful anymore but it's halfway down the crease of my groin on the left and I think I can feel something like scar tissue but not really sure as it's not too obvious. Two weeks ago, I went back on a gentle jog  (pre stretch too) after hardly feeling a twinge all week and after the first 5 mins I felt it a little bit but then it dissapeared. After the run, the numb feeling has come back and it's really doing my sweed in. I even swam on it and it has flared up again.

Any help to assist me in running again would be really appreciated.

In anticipation

Christian
