I had just got release from incarceration. I will start from the beginning, I had got incarcerated 9 months ago. no doubt im sure i was alright before i went in. I had starting eating food like i was supposed to and about a month & a half into my time i started biting my lip(I thought from dry lips) and as i was biting my lips this how it started, at first i was biting my lips and there where no bumps or sores on my bottom lip, I had bit it one day and it bled really good...it ended up scabbing up and turning black and i would repeatdely bite that one spot and sometimes it got bigger and bled most of the time as it was im assuming healing up..around a month in a half two months after this initial start it was starting to go down and heal its self...it had been 3 occasions of this happening in my 9 month time span of incarceration....I heard sometimes it was dry lips and ive been biting and others said it could be a cold sore. I did not eat directly after anybodys food trays but i would pick around their food and take what they ate and get rid of all of their touched food.....as of now im released and the last time it happened was around late September and now at about 2 days before my release(20) it has healed up and now my lips still feel dry..also this thing happened in the same exact spot everytime i would bite my lips and now as its healed if you look up close at it, it appears greyish...I have not had any bumps on my lips, just this sore everytime i had bit my lip in that place.....what can you opinonate from this post and what is the recommended action?? please give me some guidance
