What can I do for a cold at home. Feeling cold and hot, sneezing, sore throat, dry cough and runny nose. Is this flu?

Influenza usually. Manifests with severe headache, cough, and high fevers. Home remedies are antipyretics, antihistamines, cough supressants, and decongestants, all otc. Make sure you stay well hydrated, use a vaporizer, rest, and avoid allergens. See a doctor if it lasts more than a week. Good luck.
