Call your doctor tomorrow. Make sure you stay on top of it. Sending gentle hugs.

Ask the doctor to have your b12 leaves checked, low b12 and folate can cause shortness of breath.

LindaK2 I have one Ibought it when I had Covid

While you're waiting for your physical assessment you might want to order a finger pulse oximeter monitor for blood oxygen saturation and heart rate. They are very reasonable on Amazon.

Hi deon sorry to hear you are experiencing this, I have shortness of breath a lot. I'm also asthmatic but it is a completely different breathlessness for the last month I've been like this every movement and conversation I had was effort. I had a chest xray 3 weeks ago was all good thankfully.
Go and get it checked out to be on the safe side. I feel personally for myself the breathlessness comes the more I become fatigue. Take care
