My wife has CHF and while she does get tired easily, the most confusing symptom that I've actually never seen mentioned anywhere is every 4-5 days, she will get a dizzy spell, eventually lie down, and this is followed by what appears to be the dry heaves. Sometimes, she will spit every so often for a while because she said it feels like she has a lot of excess saliva.
Eventually, it will all pass and she'll be back to normal. I suspected that it might be caused by something she was doing or by over exertion, but we've kind of eliminated that.
Anyone ever experienced anything like this? Could it be a reaction to the medications?
Doctors don't seem to be too concerned about it and have never offered any explanation.
