I am very new here and just wondering whether feeling a lump in your throat when swallowing is usual with hypothyroidism. It's been there since February but lately is getting more obvious. There is no external lump that I can see. I think it may be connected to the pulsating ringing in my ears. That's been there since February. I've lost 2.5 stones in the past year and am now under weight. My thyroid levels are low but within normal ranges. T3 is 3.7 (lab range 3.1-6.8).
