I am 67 years old and have been on Levothyroxine for just over 6 years. I was alternating between 125mcg one day and 100mcg the next and thought I had cracked the dosage as I was feeling quite well. However, when I visited my GP in October last year he read my TSH level of 0.25 as being too low and advised me to decrease my dosage which I did by switching to 125mcg on one day followed by two days on 100mcg. About the same time, I fell victim to the dreaded flu/cough lurgy that seemed to be around and then coughed consistently for about 10 weeks. I have felt continually exceptionally unwell with headaches and aches and pains throughout my whole body this whole time. At the same time I have very slowly been reducing my Prednisolone which I take for Polymyalgia Rheumatica and am presently taking 3.5mg per day. I have been putting my continually feeling unwell and aching so much down to possibly not taking enough Prednisolone but am now coming to the conclusion that my symptoms are more related to my Hypothryroidism and not to my Polymyalgia Rheumatica.
My questions are -
Would I benefit from having private blood tests for my Hypothyroidism?
If so, which organisation would be recommended?
Which blood tests would be advised?
If the blood test results demonstrate that I need to have FT3 or any vitamins, would I purchase these on line as I am more or less sure that I would not be prescribed FT3 by my GP. The only blood tests they will do is for TSH and not T4 or T3 - they are extremely reluctant to do anything other than TSH levels as they seem to be of the opinion that this is the chief indicator.
If I do need to buy on line, which suppliers are recommended as providing high level products?
Sorry to be so long-winded but any advice would be very much appreciated.
