I have been hypothyroid for 12 years on treatment , in normal range yet i still have lots of symptoms what can i do ?

Nonspecific: Symptoms that are associated with thyroid disease are nonspecific, and can be due to many reasons, not just thyroid. If you have continued symptoms despite a normal thyroid level, it is most likely that the symptoms are due to something else. Occasional people feel improved when they take a combination of thyroid hormones (T4 and T3) rather than thyroxine alone, so this might worth a try

It depends,,,: It depends on what your symptoms are and also on your readings, as in how normal are your ranges. By this I mean how far into the normal range are the readings. They could be in the low normal range and you could still have symptoms of hypothyroidism. You're also on other meds which might interact with your thyroid med and also cause other symptoms. So it's a good idea to see your Dr. to check
