I ve had a cold for the last couple days - acute muscle/joint pain, congested nasal passage, headache, and sore throat. once my nasal passage clears (benadryl kicking in) and I can actually breath through my nose once more, i experience a dry and slightly painful sensation in the back of my throat. I ve tried antibiotics such as benadryl as well as naturopathic remedies. Besides seeking out an ENT, any other suggestions you might have?
