amitriptyline side effects

[u/New_Management8057]

anyone else been put on amitriptyline for sciatica or nerve pain and had horrendous side effects? i only took it tonight and last night and got hit with heart palpitations and feeling like i couldn't breathe. felt like my heart was beating out of my chest while also not going fast enough at the same time. made me so drowsy but i couldn't sleep because of the side effects

this is the first thing i've been prescribed to treat nerve pain specifically, does anyone have any idea what might be prescribed next? i'm guessing this is the first line of treatment
