My TSH level was 5.1 and normal was 5.0. Doctor suggested me to take 25microgram Thyroxine. I took it for a month which resulted to normal TSH to 2.9. Then I start taking medicine on alternate day. But after 1 month, TSH level shoot up to 7.2. Doctor suggested to double the dose. So now I am taking 50microgram dose. Last month, TSH level became normal to 3.8. But I am continuing my medicine of 50microgram. But sometimes, I feel little pain in throat. Sometimes I feel dizziness also. So should I continue with this dose? Is there any chance of permanent cure of hypothyroidism?
