I performed oral sex on sex worker a week ago since then from the next day onwards i am feeling irritation in my throat. For first 2 days i felt like im having fever also although my body temperature was normal. Now its almost 7 days my throat irritation has not cured completely as it keeps on coming. While intercourse i used condoms But now im feeling very nervous that is it all because of oral sex. Is there any chances of HIV what are its symptoms? Please doctors help me out
