What Do Nausea, Dizziness, Sore Throat And Foggy Head Indicate?
A viral infection most likely
Detailed Answer:
I read your question carefully and I understand your concern.
It is unclear how long those symptoms have been present for. If it is just a matter of the last few days then I would say the most probable cause would be a simple viral infection which can cause all those symptoms. Most times it is transitory and warrants no other treatment than rest, drinking plenty of liquids, some Vitamin C and the occasional over the counter painkiller like Tylenol which you mentioned or if that is not effective Ibuprofen.
If symptoms have been present for a longer time, over 5 days, then other types of infections or inflammation must be considered. In that case you should visit your primary physician for a physical exam as well as some blood and possibly imaging tests to determine the precise cause and management.
I remain at your disposal for other questions.
