I have severe head ache since yesterday. along with difficulty swallowing food. throat aches so badly. please advise what i should be doing? feeling so weak, mostly in bed. severe head ache and throat pain

Dr. or ER can check: Throat pain can be from a strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as sinusitis, EB virus, etc... Usually, one sees his primary care doctor if his sore throat is bothersome, recurrent, or doesn't go away quickly. "Severe" headache sounds bad and is something the ER can evaluate, along with the sore throat.
