Hello everyone,
I feel so confused. I’ve been taking amitriptyline since June and only got up to 40mg yesterday. Before I even started taking it I noticed that I would have a higher heart rate and shortness of breath, but it was usually in the morning and would go away if I did a little exercise. This started to get a bit worse right before starting ami and instead of just in the morning it would happen throughout the day. I have been tracking my heart rate with Fitbit and nowadays the only time my heart rate goes below 90 is when I’m sleeping or about to fall asleep. When I checked my Fitbit data from last December it was not like this so I don’t think my heart rate has always been doing this. My resting heart rate is also now in the 80s and it used to be in the 70s according to my Fitbit from last December. I really feel so stuck. I can’t tell if its anxiety or ami or its some kind of messed up anticipatory anxiety that I think the ami will cause higher rate and thus my anxiety causes it to be higher. I don’t know what to do. I don’t want to give up on something that might help me feel less dizzy. Any advice at all?
P.S I have seen my PCP and did an EKG to check that it’s not due to some other factor and everything seemed normal.
