Suggest Treatment For Stage 3 Thyroid Cancer Spreading To Lymph Nodes

i had stage 3 thyroid cancer that spread to lymp nodes. had TT, limited neck dissection and RAI 131 february 2013. i have been having lower back pain and neck pain for sometime. recent mri shows heterogeneous signal changes throughout the marrow with hyperintense rounded foci seen in most of the lumbar vertebral bodies. most of these lesions remain increased signal intensity on both T1 and T1 wieighted images. there is however oe lesion seen at L1 which is hyperintense on T2 and STIR sequences but heterogeneious in signal and not as readily perceptible on the T1-weighted image. on an out of phase images and is not readily visualized as well. recommending F-18 pet bone scan to rule out neoplastic metastasis. i am having numbness and tingling in hands and feet. i just started to feel some sensations in area of mouth. cervical mri shows c4-c5 foramnal encroachment on th eleft producing root impingement. my doctor said he does not see anything in Mri (without contrast) that would explain my symptoms. he said my case is complicated and wants me to see a more experienced dr in his office. he said that there are other issues that could cause my symptoms such as MS. i did not have a copy of the mri report until after i left so i thought he was just giving examples when he said MS....now i wonder if the reports suggests this. i looked at symptoms of ms and was suprised..i have suffered with migranes which stopped sometime back. however i have had a constant headache for about 8 months. in my twenties and thirties (54 now) i had on several occasions when my eyes felt like they crossed or something...i could not see but just like this blurred brightness. i never checked into it when it happened. when i was 16 i was in a car wreck and had weakness in neck next day... about a year later i woke up to no feeling in my upper body or arms. i felt like i could not breathe. i was breathing but could not feel it. it was terrifying. i went to dr and he put me in hospital. traction for a week and then he said i had thorasic outlet compression syndrome and wanted to operate and remove a rib. i did not have surgery. i have suffered with numbess and tingling thoughout my life at different times. i also suffer with vertigo (severe) sometimes lasting for weeks. i now know how to do this maneveur and it usually alleviates the symptoms after a couple of days. anyway...sorry for the long email...i am just wondering what the mri and symptoms indicate....cancer, ms or nerve issues or thorasic outlet syndrome...thanks for your time! my email is YYYY@YYYY
