back, groin, hamstring calf pain and numbness

Anyone have the following?

This past May I completed my first 5kand I sprinted to the finish line. The next day I had painful right hamstring pain and a few days later the only the right side of my groin would go numb during biking, swimming, running and long car rides. I went to the doctor in June and she said it was due to an S1-s2 compression and to use a heating pad and an anti-inflammatory.

Well, I did as she instructed but the pain never went away. The pain and numbness have increased and now radiates to my calf. I have an appt tomorrow with a neurosurgeon. Odd, that he is not sending me for an x-ray prior to the appt. Hmmm but then again insurance regulations are more stringent.

I also have bilateral knee pain from ITB syndrome and use a foam roller to work out the area. I also used it on my back; I wonder if I caused the additional symptoms to my back?

I'm scared not because the doctor might say that my pain is a result of a serious condition but of being told, "Your tri season has ended." I’m such a trigeek!
