MONO-petachiae rash after 4 weeks.

so ive had all the terrible symptoms of mono. it has been nothing short of AWFUL! now i have this rash with tiny tiny little red dots where my veins run along my body. i have been feeling better but now have this? is this normal. i had blood work 3 weeks ago and all my platelets and blood etc looked fine then. this disease has wiped my mind out!
