Hi guys, first of all, let me start by thanking all of you for giving me really good advice.
kytyree - I have not done any X-rays or similar. I've been to a GP and he says that, in this case, X-rays wouldn't show anything...
TheKaiser - About sensation, you know when you're sitting, want to get up and there's this acute pain somewhere? Well, this is it. I used the word sciatic because I've had it and it was similar, but my GP did some tests and says it is not that.
The black circle is the area where I feel pain:
It's about 12cm above tail bone, 4 cm to the left, roughly. I'm 176cm tall.
When I press it I feel nothing different.
I feel it if I ride intensely (my performance is below average, but anyway, it's intense for me).
AJS914 - Thanks, I'll look into that as well.
topflightpro - You guessed right, he gave me muscle relaxers and pain medication.
I'll see a physical therapist. Thanks
Many years ago, i also had a pain on same spot, and after few months terrible sciatica pain. In my case was the MTB injury together with a lot of sitting in front of computer, and inproper lifting. And the final result Discus Hernia L5/S1
Surgeons here suggested surgery, but i decide to avoid it until it's really needed.
And i decide to start doing excersises and streching: http://chirogeek.com/003_Exercise_DougsWorkOut.htm
Few months later, no more problems. Just to mention that doctors then give me their opinion that i wont be able to ride bike more seriosly anymore, so i had to race few months later to prove them they are wrong
(MTB XC Race, and i won in my category).
The link with excersises i give u, it's very good source of knowledge for back pain, and helped me a lot. Doug is Chyropracitc, and in the time i had the problem (2003-2004 ), he also had a problem him self, and also he was cyclicst.
Also check the Excersises Level two
Wish u fast recovery
