<s>[INST] I just saw a dentist at 3:00 p.m and i thought i had two abcessed teeth.I actually had a virus in my whole body (flu). I was relieved ,but he told me that i couldnt run or do p.e because i need rest. He gave me a prescribed mouth wash and said i should be better in 2 days. Why cant i do p.e? He said something about me heart and Im not supposed to be sweating.. [/INST] Thanks for your query, I have gone through your query. The exercise is not an absolute contraindication in tooth infection. But if you have fever or body pain or viral infection, it is better to take rest for 1-2 days till the fever and viral infection subsides. If there is fever secondary to tooth infection, then you should take rest till the fever subsides. Take a course of antibiotics and analgesics prescribed by your dentist. I hope my answer will help you, take care. </s>
