I had allergy for the past 3 months! Coughing, sneezing, specially night hard to breath! Stuffy nose. Now I have swollen lymph neck nd crank sore. Hiv?

Probably not. There is no reason to suspect HIV based on your symptoms. Allergies are much more likely. However, if you have had cold like symptom for 3 months, it is time to see your PCP. Hope this helps.
Common Symptoms. Poorly controlled nasal allergies can present with the above symptoms. Swollen lymph node could be from a recent viral infection causing worsening nasal symptoms. Canker sores are also very common. If you have had risky sexual behavior recently then getting tested for HIV is always advisable regardless of what symptoms you are currently suffering from.
