My Surgeon's office called me & they are insisting I have a Myleogram. They could not read my MRI due to Artifacts & are insisting I am weak on my R side. I am not allowed to refuse it. I can't lie flat because I have excessive Kyphosis, my head is dropped to my neck & I suffer from Vertigo whenever I lie flat. Is this going to be a problem? Has anyone had one? This is of the lumbar region. Thanks so much!
