Thanks for asking the query,
According to your clinical symptoms i suppose that you have developed a severe infection in your tooth.
A thorough clinical examination and x-ray of the tooth is required.
Start with root canal treatment
of the infected tooth.
Take a course of antibiotics and analgesics and paracetomol for fever
At home take antiseptic and lukewarm saline rinses.
Avoid eating hot and spicy foodstuffs.
Hope this helps out,
