Hi there!
do you happen to have any other symptoms...such as fatigue, exhaustion, constipation, etc? I am asking you this because i have been suffering from severe outbreaks of mouth ulcers (on my gums, back of throat, tongue) on and off for the past 5 months straight (only 5 days total in 5 months without any). Sometimes, i have 10-12 painful large sores at once. I also was tested for herpes but since i have always gotten mouth ulcers since i was little (only once or twice a year though), my doc wasn't too concerned but tested it anyways. the test was negative. it wasn't until i just had an appointment with an ENT doctor that it was established that there is an issue with my thyroid! my thyroid is enlarged and therefore, i went for an ultrasound. the ultrasound also revealed my thyroid to be enlarged. the doctor did lots of bloodwork. Needless to say, i have a follow up this week to go over all the results but the ENT was thinking at the start that i have an autoimmune thyroid disorder, where my immune system has started attacking my thyroid, which as a result, is causing the reoccurring mouth ulcers! All can be solved with medication to treat the hypothyroidism! if i was you, i would go get your thyroid levels tested and then go from there. i can not believe it has taken this long for them to figure out that all my problems are resulting from my thyroid! Good luck! keep me posted!
it would be unusual to have this many recurrences inside the mouth with herpes. at this point I recommend following up with an ENT specialist for a more thorough work up.
