Hi, I Have Been On Synthroid For Years. The Amount

Hi, I have been on Synthroid for years. The amount has been changed due to my blood tests. Lately I have had extreme pain in my hip joint. Is this a side effect and is this common? My dr has me on brand because I have lots of allergies and I may be allergic to fillers in generic.

So sorry, I didn't realize this was a "pay for an answer" site. Please disregard.
