Just from the symptoms that you are experiencing , I can tell you
that you have Hemorrhoids or Piles as they call it. They may be
outside and are called external or they may be inside and are
called internal . Yours are probably small and external causing
itching and some blood on the tissue when you wipe. You need
to avoid straining when you have a bowel movement.You can take
some over the counter stool softners Also keep the area clean
There are some creams available that contain hydrocortisone
you don't need a prescription.You can ask the pharmacist.
Also sitz baths (Warm water ) will be helpful. If problem persists
see a colon
and rectal surgeon.
