A day or two after I did a lot of walking and social activities, i noticed i was starting to get some painful bumps in my mouth, mostly behind my teeth on my gum line. I have pretty good dental hygiene and they are skin colored so im very confused what this is from. I don’t have any other symptoms of PEM besides increased fatigue for a couple days after the event, but now it’s been a week and the initial bumps are gone but there’s new ones on my upper teeth, tongue and lip now. Does anyone else get these from PEM or should I be concerned about an illness/ dental issue.
