Would appreciate some advice. I was diagnosed last May - since Aug last year have been on 100mcg levo. In Oct, GP decided results were OK and refused an increase despite residual symptoms (lots of symptoms had gone/were much better). GP felt that my TSH should not go any lower as it's already below range, and that symptoms could dissipate as they sometimes took time to resolve. Having read on here that this "symptoms can lag behind blood results by months" I thought this was not an unreasonable approach. My results at this time were TSH 0.14 (0.27-4.2) and T4 17.5 (12-22) GP said to come back in 6 months for a retest if symptoms were still present.
We are about 4 months on and symptoms are not getting any better. I have painful aching, stiff muscles all the time - the pain gets better and worse but had a bad day today and I was in pain everywhere. This is despite me doing stretching yoga most days, and getting massages from my husband, plus I do some physio stretches for my ankles. I have swollen ankles - a non-pitting edema which won't go, and get worse when my muscles are bad. I've been to the musculosketal clinic about them and they identified that I have tendinopathy in my achilles, which they think is the cause (having looked it up it doesn't look like it to me - swelling is in the wrong place). The tedinopathy is odd though as there is no normal "cause", I certainly haven't been exercising because I haven't been able to for a long time, and I have no injury - the tendinopathy is also in both ankles. I think I have started to also get tendinopathy in my elbow too.
Although my fatigue is much better I still tire easily, and can't really exercise - this hasn't got any better since Oct.
Then in Dec I started getting palpitations and breathlessness and ended up in A&E on NYE because they were so bad. They've calmed down a lot but haven't gone completely. Can I just say that I have had palpitations on and off for many years, that worsened when my hypo symptoms started; however, these have been nothing like I've had in the last few weeks. I can't sleep on my left side still because it sounds like my heart is pounding through the mattress! My heart rate is fast and I am getting lots of heart rate notifications from my apple watch when it goes over 100 when resting - which is about 5 times a day.
Do you think I might benefit from a dose increase (I've list my full last set of bloods below)? Or could my palpitations mean I need a decrease? Or am I being impatient? Feel v worried that if this isn't my thyroid it could be fibro (I have tender points where i can't be touched).
