Hi. Welcome to Healthcaremagic. I read your query. Impacted wisdom tooth may cause pain and general unwell feeling when they are errupting or infected. But mostly they are also accompanied with local symptoms as well. You have not mentioned the area. Check for any redness or swelling around that tooth area or pus. Usually pain from upper tooth may cause headache while from lower ones are radiated to neck and lower jaw. You can get an x-ray of that area to know if there is an infection of wisdom tooth and get the treatment. Else i suggest you to see a physician and get yourself medication for fever and flu like symptoms. Maintain good diet and hydration. Hope the answer helps you. Thank you!
