I have had a spell where I fainted alot. This is embarrassing to say but we have to be honest. About 20 years ago, basically when I was getting sick but had no idea, I was on hydrocodone 10 mg. It was a hot day and had stopped by a store. I felt queasy and went outside and sat down thank God bc asa I sat I passed out. My boyfriend came running out and when I sat up I saw that I had peed all over the sidewalk.....OMG...SO EMBARRASSING. After that I passed out 2 times at work. Saw a cardiologist after ER , and wore a device that I was supposed to be squeezing when i.felt faint. It never happened again. TG. Yet I feel icky sometime like I am going to faint. For me, lime usual diagnose myself. So for me. Heat, meds (& alot of them) make me feel sick. So far 20 years later I'm still kicking!😁, good luck to you and keep a watch on your Blood pressure. Happy as can be, for the holidays!
