Hi.
Thanks for your query.
Noted the history of hemorrhoids and itching of the anal area, using preparation H but not helping. There is burning sensation and that you have to itch it too much.
Your history is indicative of the following:
Peri-anal excoriation due to
dermatitis or infection caused by the bacteria of colon during defecation.
I would advise you the following:
Consult your
General Surgeon for clinical evaluation, examination, per-rectal digital examination and ano-proctoscopy.
Colonoscopy will help further to rule out any internal problems.
Once diagnosed you will need appropriate medical and/or surgical; treatment.
Take probiotics and multivitamins to have better healing.
If there is only per-anal excoriation you can go for cleaning the area with plain water and application of solution
povidone iodine locally.
A course of an antibiotic and
metronidazole may help to alleviate the symptoms.
