I'm freezing cold again and I also have humming / drone type sound in ears/head... I've had ear humming since may/June 2015 on and off... Today I'm freezing cold ... Does anybody else have this?. I also have a sliding hiatus hernia / acid reflux... I'm hyothyroid .last tsh was at 5.5 (( 0.3- 6)) .. Something like that anyway... Can anybody relate to this??? Any idea ????
