king on the river

Ok I have been lurking here for a while and found answers to most of my questions but I am having an issue maybe someone can help with. I had my outpatient surgery on thurs june 23rd and every few hours I started to I get hot all over with a headache and my temp even got as high as 99.3. I just though before that it was my body telling me to take my pain meds, but today I have not taken any meds today and noticed it happened twice after I ate. first was a Protein drink then some mushy Soup. Anyone else have this issue? I didnt feel that I ate or drank too much, just a few spoons full or a few ounces of drink. I do get a tight feeling in my chest after eating or drinking but im sure that is too be expected.
