A little scared

Me

So I’ve been fighting a cold since the weekend. No fever just really congested and coughing. Since yesterday I started to feel like my blood pressure would drop at some points and I would feel lightheaded as if I was going to pass out and I also noticed my hands and feet are swollen. Today it’s the same thing. Woke up and thought I was gonna pass out so ate something right away, came to work but still have swelling. My feet actually hurt when I walk. I’m kinda worried. I’m seeing my doctor on Wednesday for my regular appt I’m thinking to just wait till then to talk about it but still worried. Anyone else have this? Could this be due to my cold ?

TIA
