Can anyone help with advice on symptoms and testing please?
I found my way here after checking on symptoms and have been lurking trying to learn about thyroid issues, trying to figure if this is my problem. I did my own basic thyroid check through Medichecks and got these results:
TSH 1.98 (0.27-4.2)
FT4 10.8 (12.00-22.0) note "low, discuss with GP"
FT3 3.42 (3.10-6.80)
GP agreed to do tests and I thought he was running more than I did. But basically he did TSH, FT4, ferretin, CRP, rheumatoid factor, full blood count, kidney and liver function. I had thought he was going to redo my tests plus antibodies and vitamins. From what ive read here my symptoms could be related to thyroid or B12 deficiency amongst others.
GP tests had different ranges, results below:
TSH 1.05 (0.35-5)
FT4 10.8 (9-21)
Ferretin 15 (24-155)
All other tests were fine. So basically he gave me ferrous fumarate 210mg for low iron and told me my thyroid is normal.
From what ive learned on here about how ranges are calculated they seem like a postcode lottery. So ive decided to get a full set of tests done myself. I have a couple of questions before I go ahead.
1. Will the ferrous fumarate affect any of the other results and should I stop taking it before I take the samples?
2. If thyroid is the problem, or B12 for that matter, is it common for symptoms to improve and worsen on their own? I am having spells of weeks where fatigue, concentration, memory, pins & needles and aches are all severe, then spells where things pick up to some degree. Does this happen or does that mean that my health issue will be something other than thyroid related?
I feel so confused by the changing symptoms, sometimes thinking that the "virus" explanation was right, then a few days later im falling asleep at lunch break at work. It is wearing me down fast. Previously been fairly healthy so having to push doctors is new to me and I keep doubting myself.
Any advice would be appreciated, thank you. This is such a great place, I just want to thank everyone who posts, you have all helped me in some way.
