Hi there.... I ve had a risky sexual relation and 20 days later I ve had stomach cramps and diharrea, sweats and numb arms (for 15 minutes) pannicked thinking that was in the accute phase (but All I had was soft poo)... Did the HIV rapid Test and was negative, repeated 40 days after and is negative.... But turned out that I have Giardia Lamblia... I am very anxyous, heart race, dizziness, pain In then muscles for one month now! It comes and goes.... Took flagyl for 5 days and got worst, night sweats, anxiety, elbow and muscles pain.... I have very dry, pink, chapped and burning lips for a month Do you get giardia with the HIV? The 40 days Test is safe?
