Inflammation testing.

I understand that lipoedema can be aggravated by inflammatory foods (and potentially other substances), but what inflames it varies from person to person. I also have osteoarthritis which is more painful when inflamed and foods & stuff can be a culprit here too. I want to get some testing done to see if I can find out what to avoid. I know I could just try eliminating stuff, but that’s a very long winded, trial and error, process. What kind of specialist would I need to see for this type of testing?
