Hi everyone. To all the people who answered my query a very big Thankyou. I have contacted my GP and put all my concerns in a letter, especially the fact that I feel so unwell and the only blood test I had was a year ago which diagnosed me with Hypothyroidism. After 3 months of being on 25mg and still feeling so unwell, I rang him and I said do you think this dose needs to be increased. He said oh yes we can do that and wrote a prescription for 50mg without another blood test. Seems so wrong and I really do feel it is lack of knowledge.
