How Do i know if i have allergies? I mean I usually get sick at the same time every year it seems like. right now i have a sore throat, headache, and runny nose(been blowing it all day). I went to rite aid and asked the pharmacist what I can take with my symptoms and she said Clariton. so I bought it and have had the biggest headache all day. Will that work for a cold though? I need quick relief!! Anything else I can take? People always assume to drink and eat warm things but my throat LOVES slurpees, that's normal right?
