I had Covid early in November (Delta) and wasn't exceptionally ill. I stayed in bed for a week, had mild breathlessness and mostly head cold symptoms, only lost my smell, not taste. After finishing isolation I felt about 80% improved in the first week, and in the second week I felt absolutely fine. Exactly 28 days post-isolation I had my booster (Moderna) - that was just over 2 weeks ago.
For the last week I've had breathlessness that's been getting progressively worse. It feels like I can't comfortably fill my lungs all the time. This was happening every few hours about a week ago and it's now every hour. I don't want to burden the NHS right now if this is just part of Covid recovery (it's been less than 12 weeks). I'm functioning fine otherwise but it's uncomfortable.
Has anyone else experienced this? Should I be worried?
