My tsh level is 43. i wanted to know how critical that is? i am still waiting to see the endocrinologist but my symptoms seemed to be getting worse ev

TSH 43: If you feel that your symptoms are getting worse please contact your Primary doctor again. You may need to see an Endocrinologist to improve your TSH level if needed.

See pcp: you need the free hormones too to determine severity of hypothyroidism but in this case, you can see your primary care physician while waiting to see the endocrinologist to get treated if needed. the main thing for the endocrinologist is to find the cause for your hypothyroidism.
