I am from US, and finally realized I've had this problem off and on for years. Why? Because previously I thought I had a hemorrhoid. I remember now, that there were times after a bowel movement that I'd be itchy for about 15-20 min. The phenomenon would go away after a few days. Then I had this sensation that there was a hemorrhoid near my anus. It felt a little puffy, so I thought, this is the cause of my discomfort. In the past, if I had a "flair-up", I'd start using hemorrhoid creams, etc. and eventually I'd go back to my normal self. BFF with my butt. Then in Sept., 2013 I had what I thought was a flair up. Started using my usual hemorrhoid cream. After a week or so symptoms didn't go away. It got really bad. I thought, there is nooooooo way I can live like this. After over a month of total agony, I thought I was living in hell, I made an appt. to see a colorectal surgeon. Found out, that I don't have internal or external hemorrhoids. He thought it was from my recent diet change (low carb). He also informed me that that puffy feeling was actually my anal muscle. As far as my diagnosis, I really think that I damaged my skin (though doc said skin didn't look damaged) and I was paying the dire consequences. But, it was still helpful to know I didn't have hemorrhoids. So, what I've learned:
1. Skin around the anus is sensitive - Do not start using medicated creams unless directed by a doc. These creams can make matters much, much worse. Creams with hydrocortisone for example.
2. Be gentle with anal cleansing. In US, we do not have bidets. Use a moist cloth (like for a baby), to blot the anus after a bowel movement. NEVER WIPE OR USE DRY TOILET PAPER.
3. Use a cleansing lotion such as Balneol to help with cleaning. It has saved my life! You can squeeze on toilet paper and use to gently cleanse.
4. Protect the skin. I was using desitin (a product for babies with diaper or nappy
rash that is thick white cream) until, I switched to A & D (also for diaper or nappy rash). The A & D has really helped me.
To summarize, I'd like to stress that the anal skin is very sensitive compared to other skin. Do not start using vinegar or other harsh treatments. I'd start with baby wipes, Balneol (or other cleansing lotion for anus), and a protectant (A & D has helped me the most). You do not want to damage the skin.
Hope this helps you,
