I can feel a small malleable mass there, and at first figured it was an ingrown follicle, and waited for it to come to a head. It never did, it just mysteriously disappeared. During and after
that I started smelling these mysterious smells... sometimes smelled like burnt dust, mold, vomit, or a smell I can not describe... but all of them were foul. They were not accompanied by a bad taste or any strange residue on my tongue (as sometimes a bad smell can come from the mouth).
