Why would you take a before pic? Because you know there's other people with the same condition on forums like for years waiting for some good news and this is a way to prove your claim.
That's just it, it proves nothing except you had that condition at that time, and even if the after pic showed it gone doesn't mean it's a cure forever.
The reason that person had it to begin with could be different than why you have the condition. No two people have the same diet, enviroment, stress, etc.
I just happen to have an example.
In the sixties I had Ulcerative colitis, so the doctors said. Their solution was to cut out the offending colon and attach a bag for me to defecate in.
That wasn't for me, so I did a ten day water fast and it went away. Cured? No it came back. So I fasted again, but this time I cut back on sugars which I ate alot of to cure the munchies I got from smoking pot.
50 Years, or so later I still use the toilet, no bag.
If you truly cared about helping others, then this wouldn't bother you.
No bother, just trying to make you realize you didn't think it through, but it went right over your head.
