i had a pacemaker put in april last year, heart had slowed to 20bpm. i am on 10mg lisenopril and 3.125 mg 2day of carvedilol. since september , I have been experiencing prickly hands and feet and vibration sensitivity. I usually weight 152=154 have gained substantial now weight 175. I went got pacemaker tested, I thought maybe a lead was undone. They said everything fine. is this serious, or just something to get used to, I wasn t having this problem before september, I used a pr hairclippers to cut my sons hair, and it seems to have stayed. If you have any suggestions it would be helpful.
