I forgot to write that I have allergies on flowers and I take disloratadin for that.
Hi, probably it is viral pharyngitis, please try betadine gargles along with anti histaminic (you are already taking one) and decongestants like pseudoephedrine. If no relief is seen in 3 days, get throat cuture done to rule out bacterial infection ( strep etc). Pain killers like ibuprofen might help too.
