Hi all, I'm new to this so apologies for any errors. A fertility clinic wanted my thyroid to be at 2.5 TSH so advised that I go on thyroxine 30mg. My TSH when I saw them before Xmas was 4.6, then before I started the meds in March was last read at: 3.01 TSH. I asked if I could go on Armour instead as I had read many horror stories about thyroxine and did not want anymore weight gain or tiredness. The private doctor agreed. I started on 15mg of Armour but it appeared too much. I had headaches, confusion, anxiety and racing heart. I cut the right down in the end to just: 3.75mg (4.00am) then 3.75mg (12.00). I tolerated this really well and steadily increased to 15mg and split in two doses at the times of above. I then tried to increase to 20mg, too much - heart raced. Then to 18.75mg and appeared too much so went back to 15mg. In the last 3 weeks I have had clenching feelings in my heart. It's not anxiety or panic, it feels more muscular. It feels like someone has a hand around my heart and is occasionally squeezing it? I've also been suffering with terrible bloated stomach destination and acid reflux. I have had bloating and reflux many times prior to taking armour plus I had two key hole operations last year (April / October) to remove endometriosis and Fallopian tubes. My stomach hasn't gone down since. My gp has given me the following to help with the bloating and acid. Ranitidine 150mg X 2 per day and 10mg Dompetidone per day. The gp believes that the heart and I should have mentioned prior, the left side rib pain is due to the diaphragm being pushed up and destended from the bloating. I have not told the Gp about the armour as they did not want me on any thyroid meds unless my TSH was 5+. I've not taken Armour for over a week but the pain in the heart had not stopped. I feel a lot, lot worse, very tired and tearful. My resting heart rate over the last few weeks had not changed it = 74bpm. Please, please advise as I'm very worried and unsure what to do and concerned I've damaged my heart with the Armour.
