I'm really hoping someone can give me some advice. I have underactive thyroid (diagnosed approx 7 years ago) and now take 125mcg Levothyroxine. I honestly don't feel as though it's doing much. My weight has crept up, hair gone really fine and just sick of generally feeling unwell. I get one throat infection after another, often feel achey and terrible IBS. I'm at the point of wanting to see private Endo specialist and wondering if anyone can recommend one. I have done a little research and see there is an Thyroid Clinic in Harley Street. Has anyone been? If so did it cost a fortune? I live in the North East but have family in a London so traveling there isn't a problem. Hoping someone can help.
