Have had an issue with my perineal and anal area before and after using the bathroom.  A BM odor persist letting me know that I will soon need to make a BM, then after the BM the odor is still there but not as much.  I decided to use babywipes (nonscented) and it used to work, only to find out that I have extra skin folds that move in and out of my anus due to the OB/GYN stiching me up wrong and causing this issue that I have now.  If I go to the bathroom the odor is horrible, I will now need to take soap in the stalls and wash everywhere below to git rid of the odor and as soon as I do something strenious, the skin moves out and starts over again.  The odor is non-stop.  Even after washing it does not go away.  The skin is so thin and sensitive that after washing it becomes sore, irritated and burns.  Beginning to think its something internal going on.  Tried collagen, biotin, vitamin A, E and C oils on the skin to build up skin tissue.  Does not work.  Some days are better than others.  Last year for a week, I had no problems at all with odors.  Then, it slowly returned creating odors that were stronger than before.  Everytime it goes away it comes back with full force; worse everytime no matter what I try.  Researched pelvic floor weakness as well.  Will be my next step along with getting a biopsy of the skin.  Could also be contact dermatitis.  I do have a long list of allergies.  Allergic to almost everything under the sun that may get on the skin.  Was not always like this.  Started over 12 years ago and seem to get worse every year.  Remember 2 years ago that I could not be around scents at all because the odor would get on me.  That was fixed after I fixed cavities in my mouth that made my lymphnodes get bigger and my skin issues were worse.  I can now where scents again but it does not help my thinning skin issue.  My other issue that I have is after I eat certain foods that I get an odor such as chicken, tuna fish, beef.  Makes me smell like rotten meat.  That went away at one point too then I see is gradually coming back.  I drank aloe juice straight from the bottle for a week.  HORRIBLE TASTE, but it worked. I took it because I was told that I had an ulcer from a GI doctor then went to another and my records did not indicate that only gastritis.  Strange but true, the new GI doctor told me that I had gastritis too and mysteriously the ulcer was not reported, it was not placed in my medical records.  However, after drinking the aloe, the odor issue after eating foods went away and the other anal and perineal odor went away as well then slowly came back.  Maybe, I should try that again.  Been feeling like something is tearing in my stomach like small sharp stabs which just started.  Now, I need to look into that as well.  Have itchy foot with small prickly bumps that do not go away, was told that it was contact dermatitis.  It may all tie in together other or just 2 seperate intities.  No matter they are strange issues for one person to endure.
