Hello Doctors, I have had feeling daily tingling, sometimes sting and observed red small spot on my chest, hands with itching since 1.5 months. I had consulted the doctor and gave me fexofenadine medicine for 7 days. I took 7 days dose and NOT recurrence (OK) during 7 days dose, but after finish the dose, next day I feel the same red small spot on my chest, hands with itching and after 30-60 minutes automatically disappear. I also discovered cherry(Blood vessel) : 1) Leg, 2) Hand 3) back side 4) shoulder – there are four cherry I observed. I am too worried & not focus on my job because 3 months ago, I had unprotected sex with unknown girl during menstrual period in unconscious condition. The HIV report says non- reaction after 80 days exposure. Appreciate if you could give me the right advice with adequate solution whether risk or not. Thank you.
