Hi Laura. I'm sorry that I'm just now reading your post. You've had such a rough time! I like my cardiologist and I'm sure once all the tests are run and he gives me the usual "it's lupus" I'll keep him in mind as a resource. I hope your cardiologist has done a complete workup on you. I'm sure you know how serious A Fib can be, plus both extremely low potassium and/or calcium can cause heart failure (that's the lab in me talking). Eat plenty of bananas (K) and dairy (Ca) along with your meds.
I'm so glad school is almost out for you. My cardiologist wants me to take it easy until we find why I'm SOB, but hearing you walk makes me want to walk too. Perhaps, like you, I'll go with hubby so he can keep an eye on me.
I just bought a bathtub caddy that has a reading rack. Ah the wonders of lavender Epsom salts and a warm bath! Do what ever eases your mind and you find relaxing. Love, Donna
