I was also circumcised as a baby. (I'm male, too) I just think that it was kind of "un-natural" to have that done on me, without know what was going on. I like it I guess, maybe it helped in other ways. But I still think it's violent and causes physical trauma. I like it now, I guess, since it's over & already happened when I was a baby.
But I was thinking.. Imagine as soon as you're born you get a violent circumcision? Wouldn't that be kind of un-natural? A violent pain for a baby? All of the pain/energy has to go somewhere, it's like a violent physical trauma. Your brain could be changed, your immune system can change, and a whole bunch of other things could happen as an effect from that. It's pretty violent in my opinion... especially for a newborn.
I obviously don't feel it now, I feel pretty normal. But I'm just saying, back then I could only imagine what it felt like... How did it affect us? But circumcision is probably a smaller contribution to EC. I think that EC was exactly caused by direct physical trauma to the lips. Of course, other things led up to EC and made small contributions here and there. But I think initially the real cause of EC when someone first "GETS IT" in someone's life is a direct physical trauma. In your case, someone bit your lip? THAT'S what I think caused your EC, in my opinion.
From all of the data I've collected over the years, there's always direct physical contact to either the upper or lower lip, and from there it could transfer to the lower or upper lip, as well.
There are tons of physical trauma possibilities. (I also think mental and physiological trauma play a part because like stress and other mental traumas, it's a real physical thing going on in the brain and body can be affected by mental trauma as well.)
Examples of physical trauma:
-Direct hitting, jabbing, slamming, pinching of the lips.
-Smoking (decreases oxygen to the lips and causes dry lips, high heat, etc)
-Lip licking (components in saliva can cause lip lickers dermatitis, dries out lips, damages lips)
-Harsh substances (lemon juice can destroy the lips protective layer, etc.)
-Steroid creams (these cause more harm than good on lips from my research)
-Picking, peeling, of the lips. Picking at the lips and peeling them until by accident then ripping off by accident and it starts to bleed. Touching the lips with fingers, without realizing it, playing with them, this is physical trauma which damages the lips and causes harm to lips)
-Cold weather, in extreme cold the lips could dry out, and if you combine that with smoking your lips will get damaged.
-There are so many more physical traumas to the lips that could have caused EC.
-Mental trauma could also play a small contribution leading up to EC. Stress is a real physical thing that causes harm to people's bodies. I think this one is a little underrated, but mental and psychological traumas could cause some damage too.
All of that energy has to go somewhere, it may have contributed to physical health problems in certain individuals.
