i hurt...

ok guys...need some advice...from anyone...

I have been running more than I ever have before...
Thursday...8 miles
Saturday...26 mile bike...6 mile run
Monday...4 mile run
Tuesday...3000 meters swimming...4 mile trail run

I AM IN PAIN!!
The back of my right upper thigh...where it meets the butt!

It hurts to walk...I am living on Advil and Motrin...it hurts to sleep on my back...

Any idea what it could be???

I am really contemplating calling the doc....i am gonna take tonight off from running...maybe!
