I have cold symptoms of sore throat, mild cough with clear mucus, & runny nose. also have upper chest pain and threw up mostly mucus last night??

Cold symptoms: Try NSAID like Aleve (naproxen) for pain and fever, decongestant with guaifenesin decongestant like mucinex and cough suppressant like dextromethorphan if needed. Hot shower, sleep with head elevated, vitamin c, hydration and soothing beverages helpful. If pain or fever and symptoms persist 10 days or green/yellow secretions and fever see doctor. Good luck.
