That stinks!!! I am so sorry!

You should get the thyroid thing looked at by whatever means they recommend - if they don't think needle is appropriate, suffer through the dye. It is worth it to be as thorough as possible and catch any potential issue. (Trust me, the thyroid biopsy stinks!!)

Good luck - take care and don't get too down about all this. You will heal and this will pass. You need to take care of your body so these will ony be speed bumps and not permanent road blocks. This is what I'm dealing with as well now. I can't ride for 3 - 6 months while these anti-coagulants break up the clots in my lungs. It sucks, and I am missing two double centuries and a 508 mile race I have been planning for all year, but I figure it is better to be completely thorough and diligent and do what is best for my body right now so I can come back with a vengeance next year.

See, this way we get to have a real honest to goodness "comeback"!!!
