25yrs ago I was diagnosed with hyperthyroidism. I was on carbimozole for quite a while but after regular blood tests I had radio active iodine. This however caused hypothyroidism and I was prescribed 75mcg levothyroxine. Several years later a blood test showed that this was possibly too much so reduced to 50mcg. I have been happily and successfully on this level for about 12 years. I also have high blood pressure and am on 5mg of Amlodipine. As a result my BP has been normal.
Now however, suddenly my BP has shot up (to anything between 158/80 to 180/90!), I have a pounding heart beat, lots of ectopic beats and waking in the night and first thing in the morning with anxiety attacks, none of which I have ever experienced before. My GP sent off a blood test for thyroid and it apparently came back normal for someone on Levothyroxine.
Please tell me ........is it at all possible that all this is being caused by my thyroid and the levothyroxine, after all these years needs adjusting? I just don't want my GP to alter BP pills if its possible the cause lies with my thyroxine pills.
