Help! My nose was running yesterday, ears hurt, and teeth started to ache; what is it?

I am away from home in Florida so can’t get to my regular doctor or dentist. It was very rainy yesterday so I thought it was allergies (streaming nose.) I took a benadryl at night, woke up in the night with aching ears, sinuses, and teeth (left side only). Took another benadryl and still feel bad today but not as bad. Is this a sinus infection, cold, allergies or tooth problem (snot was clear)? Should I see someone or wait another day? Dentist or doctor? I fly home on Friday.
