Thanks for using Healthcaremagic,
After going through your details it seems that you have stopped carbimazole without consulting physician.
Your symptoms may or may not be due to hypothyroid state, hence please consult your Physician/Endocrinologist
as soon as possible and get Thyroid function done like FT3, FT4 and TSH.
If tests show hypothyroidism
then even low dose Thyroxine may be given to help in recovery.
There may be other causes of incoordination
like MRI brain will be very useful.
If appropriate serum electrolytes, kidney function,complete blood count
and liver function test may be required.
Hope this information helps and wish you good health.
Dr.Akhilesh Dubey M.D.
