Rach, I think keeping it as short and brief and formal as possible is the best way to go. Don't offer up a lot of details. Just say that you would like a second opinion on your condition, which consists of fatigable ptosis, generalized weakness, oxygen stats dropping into the 80's, etc. And then ask if they can see you and do testing to figure it out.

Really, you don't have to say any more than that. Let the doctor take the lead. You'll probably get a response within 24 hours.
