Why? You are obviously hypothyroid and should be on meds. TSH is over range, free T4 is rock bottom and free T3 is almost under range. You should get a prescription for 50mcg levo immediately and start taking it. Your adrenals will be stressed by trying to compensate for low thyroid.
How much Levothyroxine were you taking when you had the blood tests above done? You were undermedicated. GP should have increased dose not stopped Levothyroxine. Your GP can investigate adrenal function without stopping Levothyroxine. You should resume Levothyroxine and ask GP to increase dose.
The goal of Levothyroxine is to restore the patient to euthyroid status. For most patients that will be when TSH is 0.2 - 1.0 with FT4 in the upper range. FT4 needs to be in the upper range in order that sufficient T3 is converted. Read Treatment Options in thyroiduk.org.uk/tuk/about_... Email dionne.fulcher@thyroiduk.org if you would like a copy of the Pulse article to show your GP.
You should ask your GP to check ferritin, vitamin D, B12 and folate which are commonly low/deficient in hypothyroid patients. Most symptoms will be due to low thyroid but heavy periods can be due to low ferritin/iron too, painful joints can be due to vitamin deficiency and pins and needles in hands and feet can be due to B12 and folate deficiency.
