Hi, I'm new here so forgive me if I come across at all clueless. I've written quite a lot but if anyone would take the time to read and help, I would be very grateful.
I recently went to my GP and had a blood test for TSH, which came back at 2.7 (which I was told was within range). I had the test at 9:30 in the morning, with no breakfast before since I was advised that it helps the accuracy of the test, so I trust that it's a fair representation of my TSH, but my problem is that my symptoms seem to be getting worse. My bp is normal but my pulse was 57bpm (a tad low). I was told ferritin was normal too.
A bit of context of my symptoms:
I suffer from being very cold, and even when I dont feel cold in myself, my hands and feet are always cold to the touch, feel numb/tingly and appear grey.
I also experience extreme fatigue, even standing up and walking around for too long tires me out (i dont get out of breath, I just feel wiped out). I have very bad constipation, I simply can't go, and even when I just sit it out and wait up to 2 weeks for it to happen, I end up becoming impacted (my doctor gives me laxatives on the -impaction dose).
I also have terribly dry skin, especially behind my ears, my arms and hairline. What started off as dandruff is now becoming sore and scabby, bordering-on psoriasis with hairloss. My girlfriend is a training-hairdresser and she cannot find a cure to my dry scalp, even with all conditioning and moisturising treatments.
I cannot lose weight, I've tried a low carb + reduced calorie diet (high in protein and vegetables) because I was gaining weight at a crazy rate for no reason. I manage to maintain weight on this diet, even though I'm pretty sure the average person would lose a little bit. I went on a skiing trip, and ate what everyone else ate, abandoning my low carb diet but only for 2 weeks. I noticably gained a lot of fat, and the scale went up by 8lbs!
I feel so miserable, tired and cold all the time, and I feel I'm more like 70, not 17.
It is worth mentioning that my dad has hypothyroidism, and so did his mother. It was him who suggested I went to get tested, as whenever I mentioned my symptoms to anyone else, they wouldn't take what I said seriously as I'm young.
I also had anorexia when I was 14. I have been fully recovered for 3 years and since have even been overweight again, but I feel the symptoms I described have been getting increasingly worse and noticable since my eating disorder. I'm not sure if an previous eating disorder could affect the thyroid?
My GP tested for TSH which came back normal and he said he is satisfied. My question is, what do I do now?
Is it possible that my thyroid is underactive even with a normal TSH result? He didn't test T3 or T4, so should I get an appointment to test that next? or does a normal TSH rule everything out?.
I really just want to feel better, and since my symptoms line up and it runs in my family, it seems plausible that my issues may be thyroid related, so should I carry on exploring that option?
I know that was a lot to read, any responses are welcome, and if you think my symptoms line up with another condition, please share.
