I am new here. I have been taking prilosec for about 4 years now (20 mg) and 2 days ago I started having really bad joint pain. I am wondering if this could be related to the drug... I would appreiciate any thoughts on the matter.
Thyroid-Stimulating Hormone (TSH). Guide. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.
T4 (thyroxine) Test. The thyroid gland produces T4 (thyroxine). The free T4 and the free T4 index are blood tests that, in combination with a TSH test, can let your physician know how your thyroid is functioning. The pituitary gland tells the thyroid how much thyroxine to produce through signaling by TSH.
