I have family history of hypo and over the years I have checked my tsh level occasionally (used to work in a go surgery so used to do up my own), they always came back normal. However having done some research on symptoms I was shocked at how many boxes I ticked overweight (cannot shift despite training and dieting!), depression, seriously bad concentration! Puffy hands, tiredness/exhaustion regardless of the amount of sleep, constipation, sore neck, pins and needles in hands, fluid retention, body unable to recover quickly from infections (I am on my 6th antibiotic for an infected navel), headaches, blurry eyes (just had eyes tested and they are fine), muscle ache
Maybe these could all be something else but with the family history I'm not convinced it is....don't want to be fobbed off by the gp so would like to go armed with some knowledge.
