After 8 years exposure, i have a negative tridot , negative western blot and negative pcr rna. But im symptomatic for two+ months? I have seen two doctors in person who said theres absolutely nothing wrong with me. But if its not hiv what could be the reason of my weight loss, loss of libido, loss of appetite(it has improved now) , tiredness , vision problems(consulted a eye surgeon, he said theres no problem in my retina), dry mouth, shortness of breath. Is there still a chance for hiv? Or what else could it be?
