IF someone actually shows signs of infection...it comes at 2-4 weeks after infection and lasts for 1-2 weeks.
you state that it has been 12 weeks since your exposure. you can test now for a conclusive test result, if you have not done so yet.
I have just returned from my physician who has looked at the spots on throat and said they are normal and that any spots on throat or indeed any of the other burning/tingling sensations i am experiencing would not appear this ealy after possible infection. I am going to do retest for piece of mind but my doctor states that the 7 week negative test will 99% be negative again unless I have had another exposure, which I haven't, would you agree with his comments???
if you tested 3 months after exposure, then you have a conclusive test result.
I can only repeat what the doctors have repeatedly said (and these doctors have impecibale credentials). Your symptoms are meaningless. Understand that, meaningless. The doctors themselves say this, and they have spent 30+ years studying and working in the field, they are expert doctors and would not lie. So, 12 weeks later, get tested and you will be in the clear. Also, take it from me, the mind can play crazy games with your body.
