Hey about 2 weeks ago I had oral sex from a escort and ever since then my throat had become worse and worse I cough while their is no symptom of me being sick and it's growing the pain all over my throat from the very bottom all the way up to my nose breathing area. I cough and it's a severe pain every single time I cough as if I'm coughing to just rip my throat open. Could this mean I have any illness in the std department. I don't have any other side afford like pimples or pimples on my penis or anything else, however I do have severe headaches here and their but that might be because of my glasses. I feel weak as well I really can't do heavy lifting or heavy exercising . Could any one please help me?
