I have been taking 60mg of amitryptiline and now my Dr prescribed me 30mg of Duloxatine to take. Since I started that, I’ve been having the shakes and now my thighs are sore and can barely crawl in bed. I also just got out of the ER and was tested positive for Influenza and had to have Potassium given through my IV cuz I have a tendency to get low quite often even tho I’m on 2 potassium sparring diuretics. My body just doesn’t hold the potassium molecules for some reason and my Dr can’t figure it out. Does anyone else get the shakes when they started taking both the 2 meds together? I’m so lost and unsure what to do.
