I'd like a physics level explanation.. when those molecules are there? whats going on at the atomic level, is there an excess of negatively or positively charged molecules ? When there is inflammation, there is usually heat, and heat means energy.
Lots of things can be going on. One of the most dramatic things is the respiratory burst of neutrophils. https://en.wikipedia.org/wiki/Respiratory_burst. But neutrophils are not the only inflammatory cell and not all inflammatory processes involve them. There is way too much to describe in a comment on the internet.
