I just read Dr. Lapp`s tip of the day.He advises frequent rest, light areobic excercises and low stress. I had`nt been out of the house for a few days because I was feeling really miserable and in a lot of pain.Today I forced myself to do some needed grocery shopping ,took my dog to be groomed and insisted on going with my husband to pick her up. Well, I could hardly get back in the car with her,sat down and immediately went to sleep.My husband got dinner, I ate and back to sleep again.Later tonite I thought I was having a heart attack.tight pain in my chest and back + down my left arm. It hit me twice and I thought sure it was my heart. My husband said my pulse remained steady so I am assuming it was that I over did when I was really too tired to do anything. I just felt that I needed to exercise in some way.Any comment on what anyone thinks happened? I would hate to think that I am not going to do anything any more.
