I have recently been diagnosed with hypothyroidism with my TSH at 13 and have started on 88 mcg of synthroid since the past one week. I am observing that synthroid is actually making my symptoms like brain fog ,memory loss and cold intolerance worse. Is it normal for synthroid to act in this way initially? I believe I have been hypothyroid for the past 2 years with my TSH oscillating between 5 and 9 but the medication started only recently. Can this be a probable cause of worsening of symptoms?
