Brief Answer:
Most likely haemhorrhod grade 4 or anal vein thrombosis

Detailed Answer:
Dear Patient,

You haven't mentioned if it hurts and/or itches and if it is more skin colored, red or blue and what the approximate size is, so feel free to let me know.

From your description so far there is 2 main possibilities.

1. it can be a prolapsed haemorrhoid grade 3-4. Typical is that appears more skin colored or redish and it hurts/itches. That would have its start in the inner part of the anus. Mostly a small, noninvasive operation through a proctologist is necessary when it is grade 3-4, different techniques are available like so called sclerosing or ligature. If it is a haemorrhoid grade 4 unfortunately it will mostly not go away by itself.

2. it can be anal vein thrombosis (often times mistaken for 1.). This is mostly also painful and more bluish colored. In difference to 1. it comes from a vein thrombosis of the outer part of the anus and is not a real haemorrhoid. This can be treated with special sitting baths, some cream with local anästhetics and will often times go away by itself. Only in some harder cases a proctologist needs to do a small cut to open it.

A friction blisture or other condition seems less likely to me from your description so far.

So what i would recommend if you were my patient is the following: try treating it first for a few days with a cream with local anesthetics for haemorrhoids and warm sitting baths.
If it doesnt get better, a proctologists needs to have a closer look at it since that is the only way to distiguish for sure if it is a real (prolapsed) inner haemhorrhiod or outer anal vein thrombosis ("fake haemorrhoid") and he will evaluate if a small operation is best for you or if this can be avoided.

Hope this is helping you , if you have any clarificatons you can get back to me, if this was helpful please kindly rate my answer. Best regards
