I'm about 4 weeks post surgery, and for the most part feeling well. The only weird thing is that when i do the least bit of activity (walking, standing) i can take my pulse and it feels like a weak pulse that i can just barely feel, then a regular pulse right after it. It usually feels like this until i sit down. I didn't think these were extra beats, just because there is no pause in-between them. Is this normal, has anyone else noticed this? I may just be paranoid.
