I have looked through the forum and found other post about hips, but none describe the problem I have.
I have experienced this on 3 occassions at events but never in training (I do about 14 events a year). It has happened twice in a half and I have run through it, and it happened again on Sunday in a marathon and got so bad i had to drop out at 22 miles.
Basically, it starts as a dull ache across the back of my pelvis at hip bone level. I is quite deep ache. On each occassion it has kicked in at about 12 miles. It then gets steadily worse and then goes down into my hamstrings. I do not feelit over my glute, just in the band across the back and down the hamstrings.
On Sunday i ran with it and it was bad by 15, into the hamstrings by 16 and agony at 19. At 21 I slowed to a walk thinking that I would run walk, but at that point I could not control my legs proerly and started to stagger. The support team sprayed my legs and gave me a rub down and i tried to continue but had to stop at 22 as it was too painful and the pain made me vomit.
It always seems to clear/reapir within a day or so. Yesterday I was stiff and painful - not ache but sore - but i kept mobile stretched and massaged and today It feels a lot better. I reckon I will be running agin by the end of the week.
Has anyone got any experience of this? I am really keen to try and avoid it happening, and find it strange in that it only happens intermittently?
Also, has anyone got any idea of what type of specialist I should consult?
