Do you recall what antibiotics you took? Some have lingering problems with mito damage.
Pericarditis can be from inflammation or viruses too.

My son's math teacher in high school developed a serious case of this from exercising/lifting weights while having a flu. He was also a coach and PE teacher, and rather addicted to daily exercise and the virus went to his heart!
I hope your doctors are doing autoimmune testing for lupus, and the other inflammatory things on the list at the link I gave today.
