I'm 24 years old, and woke up at 4 am with severe chest pain. I found that when I burped, the pain subsided. I thought it was gas, so took I two GasX pills. About 20 minutes later, I vomited. Since then, I have vomited twice, I've had severe body aches (everything hurts), a throbbing headache, chest pain, a constant stomach ache, and fever. Should I go to a hospital?
