Just wondered how many people experience shortness of breath just laid in bed? I feel like I can't breathe despite laying still and doing nothing. I've had it for years but nothing seems to help and I still have no idea what is causing it, it seems to come along when I'm at my worst though and when my exhaustion is at it's worst too (having to be in bed 90% of the time). Does anyone have anything I could do that could help it? I have the usual relaxation cds but it doesn't really help. I had severe B12 deficiency which I've been treated for for the past 5 years but still get this uncomfortable symptom. I'm dx with POTS too but although my heart feels uncomfortable currently, it's not particularly fast (around 70-80 laid down). Any ideas? Thanks.
