I've been on armour about a week and half for my hypo and have just recently started to feel some side effects. I've started getting some pains in my chest, it feels like it's right up under my heart, mostly during the night or in the morning. They don't really last long but I definitely notice it when its there. I am also very aware of my heart beat, even though it's not racing and at a normal rate, around the time these happen. I know that this is a side effect that you can experience while on armour. My question is, is this something very serious?? I am due for a testing in two weeks to see about correcting my doseage. Is this something that can wait and be fixed with a dosage correction?? Armour so far has taken care of about 75% of my symptoms and I'm hoping that after this next testing, I can make it 100%. I have read so many good things about this and it seems like it is beginning to work just as well for me but is this a sign that I am just not compatible with this drug??? Thanks in advance for any and all input.
