Hello and welcome to HCM.
Thank you for your query.
I understand your concern. And from your description, it could in fact be hemorrhoids, but without a physical examination, it is difficult to accurately diagnose.
If it is indeed a hemorrhoid problem, then yes, they are harmless, but in the long run can result in symptoms like bleeding stools,
constipation, pain, itching around genitals, etc. So you should visit a doctor, who will help in treating them. Yes, you can easily get rid of them, but only with a doctor's help and advise.
They are not self-resolving, and only get worse with time. So I request you to please visit a doctor.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
