i have blocked ears hard to hear. bad allergy symptoms sore throat, head ache, ear pain, itchy eyes, nasal drainage,and pressure. i have a bump/knot in the roof of my mouth could this be from my sinuses. i feel like i may have a bad infection. Cant get in the doctor until 2 days from now, i have left over amoxicillin, but im afraid its not strong enough. should i go to er what will happen if it ruptures.(the mouth sore)
