This is my story....I was dating this lady for about three months....since the very beginning ive asked her if she took a herpes test and said yes ....right after her last long term relationship. and have not been with anyone else after that just me.....and takes all the tests including a herpes test every 6 months....we had intercourse numerous times....every time protected....i never did oral on her until the end of our relationship...which i regret for the symptoms i felt and feeling till now....at first when i did it....i felt this burning sensation all over my lips so i stopped giving her oral ...something i never felt before giving oral to my past relationships....i told her about it there and then and she was like shocked...so i went to the bathroom to wash up my lips with water....ok...then like two days later i got this white blister under my tongue....on the bottom of that elastic part on one of the little gland type flesh...hurt a bit...but i do remember having that same thing one time with my past relationship which was years ago on the same spot after oral....so i thought i was a bacterial infection that i got from giving oral sex....it cleared in a day or so....sooo.....we didnt speak about a week...so after that 9 days later it was a hot day i was out....and started feeling this tingling burning on my lips..which was june 1st....now its june 21st....and still feel this but mostly at night...i have not have a sore or blister.....all this time ive been so worried ive gotten infected....because of this ive had nights with little sleep and feeling depressed, looking up information on this....been to the ER, they checked me out they said they dont see anything that would resemble it that it was anxiety related.......i went to another doctor to get a check up and took a few STDs test except HIV and herpes..they didn't have a herpes test there....i'm really hoping its something else....because im been really depressed about this.....now the tingling comes and it goes...in the morning im fine if i rested well....afternoon sometimes....but the burning starts at night around 10:pm. and last a while but doesnt look sore at all...i put a bit of promegranate lip balm eat a bit of yogurt kinda helps then it makes it go away and it stops... but sometimes crawling or tingling happens but minor and goes away....im not sure if it could be an infection of some kind lasting this long or what...please help im so worried what could it be,,,,,ive read other people with the same problem lasting this long these symptoms and no sores....not sure if there's ever stopped or what happened to them....but most were concluded with that they were very obsessive of thoughts this like i am.......sigh
