More blood work done. levels complete opposite. gp changing dosage again. should i see endocrinologist?

Maybe.: If you have a lot of questions that aren't getting answered you should discuss with your provider or consider asking for another opinion.

Need more info: Don't have enough information . Would need to know lab, levels, doses, medication, etc. Would not hesitate for you to see an endocrinologist if your initial doctor has problems or questions.
