i am sure that this sucks in more ways then one and am sorry to hear about your perdicament, that being said i have to ask, have you talked to a Chiropractor about this?? i know some people dont like them or trust them or have never been to one to understand it or them but the right one can do amazing things when it comes to skeletal problems. if your tailbone is not positioned right and can be severe pain in the azz (pun intended)and i know it is no laughing matter first hand. i cracked mine some yrs ago (oh the jokes that were told about that

) and untill i seen a Chiropractor, i found no relief. i hope it all gets better for you but i wouldnt let a doctor investigate nothing when it comes to skeletal problems. it could be just tipped a little and a doctor or boneguy or nuroguy wouldnt have a clue and would have you jumping thru all kinds of hoops or taking drugs and all the while it could have been clicked back into place and problem cured with just a couple of visits to the right kind of doctor. good luck and like others have said, dont give up on the bike just yet, if they find the problem and fix it and you have sold your bike, you will be regretfull about it.
