While sitting peacefully getting my long-awaited pedicure, I noticed a heaviness/pressure on my left side, under my arm. My left shoulder and upper arm feel heavy as well. There's a pressure in my back and my neck, I feel absolutely drained, but I'm restless, trying to find a comfortable way to sit. I didn't get up till noon, ran a few errands, and visited B for about an hour. Hubby is fussing at me about going, but I've really had enough hospital this week to last a while. Should I let Hubby take me to the ER?
