Starting Sunday 9-25-16, I had a burning sensation on my lower lip soon after my husband and I got done eating. Monday evening my lip got really red, swollen, tender. Tuesday morning I started having loose stools eventually turning in to diarrhea. My stools since have still been loose, but foul smelling. I've had the same symptoms for the past 12 days. Both of my lips are swollen and tender, lower lip the most. With what looks like a rash. Urgent care said I had an allergic reaction, but the doctor I have been seeing thinks its a primary oral herpes outbreak. I haven't had any blistering, but a whitish bump appeared behind my upper lip 2 days ago. No pain in it, but its there. I'm fatigued and just really want to know what's going on. Any help would be appreciated.
