I feel a virus infection coming up, my throat hurts when i breathe in deeply. I think my hcg somehow got infected. Is there a way i can protect against a viral infection? I took aspirin 250mg hope that will help. I got pericarditis 2 weeks ago, started the same way. But didnt know why. Now i think something is in my hcg-a virus i think. I took 2,5ml of the solution last few days. hope i will be ok and im not going to doctor yet. its just slight pain i feel. anxious because of that.
