### input:
I have been having trouble for 6 weeks.  First symptom was my left eye was frozen midline with diagnosis of cranial nerve paralysis with associated diplopia.  I have no thyroid since 2011 disected totally for CA, synthroid 200mcg for the past year.  My dose was dropped to 175 mcg when labs were drawn when the eye paralysis occured.  My muscles in my legs were painful and got more difficult to walk.  10 days ago my right leg was extremely weak, buckling at knee and with a foot drop downward and inward.  The left leg was also weakening. Labs were done and my Synthroid was dropped to 125mcg.  I was transferred in 4 days to an advanced hospital for diagnosis assist and they dropped my Synthroid to 50mcg.  It was dropped from 175-50 in 4 days.  The physicians continue to tell me my thyroid must be making more hormone however...I have no thyroid.  I did not take the radioactive pill post op because  I had a young child and no one to take him while I was radioactive. Could this weakness be caused by over compensation of Thyroid replacement?  Should I have an uptake scan to look for reminant thyroid tissue?

Hello! Thank you for asking on Chat Doctor! I read your question carefully and understand your concern. Your symptoms seem to be related to mononeuritis multiplex, which is an asymmetrical type of neuropathy, related to your thyroid dysfunction. Hypothyroidism (low thyroid hormones) can lead to fluid retention and pressure surrounding nerve tissues. So your symptoms can indicate a low dose of thyroid hormones' intake (you need to take more).  So you should consult with your attending physician to perform some lab blood tests : - thyroid hormone levels-fasting glucose-complete blood count-blood electrolytes- kidney and liver function tests, etc., to exclude other causes of neuropathy. Hope to have been helpful! Best regards,
