While it is always best to be seen by your doctor, this does not sound like a penis fracture. Here is information on what types of symptoms a fracture would cause https://www.medicalnewstoday.com/articles/318566.php. Things like bleeding from penis, issues urinating or keeping an erection, extreme pain, etc. You clearly hurt yourself a bit but it doesn't sound like a fracture. If the symptom you are noticing continues, do see your doctor.
The characteristic symptoms of penile fracture are a “snapping” or “popping” sound, penile .... Physical examination revealed mild, very distal penile edema and ...
After researching my symptoms online, I have discovered that my symptoms do actually match Peyronie’s disease (https://www.healthymale.org.au/mens-health/peyronies-disease). I know searching the internet isn't always a good thing, however, when reading through that link, the following does indeed sound like what I am experiencing:
What are the symptoms of Peyronie’s disease?
Peyronie’s disease begins as a small swelling or inflammation, which hardens into a lump on the upper or lower side of the penis. It usually develops over time, but sometimes appears very quickly.
In most cases, you can feel a hard lump at the point where the penis curves.
Peyronie’s can be painful, reduce flexibility, and in most cases will shorten or create a bend in the penis when it’s erect. In some cases, the shape of the penis changes so that there’s an hourglass deformity or constriction to one side.
In the early stages, you might experience pain when getting an erection. In mild cases, where the lump does not cause the penis to bend very much or at all, it will only have a minor effect on how you experience sexual intercourse.
However, moderate or severe Peyronie’s can make sexual intercourse impossible because of the shape of the penis, or problems with getting an erection. In some cases, the penis only becomes hard up to the area of the scar and stays flaccid (not erect) past that point.
You might notice Peyronie’s after an injury to the penis. People with Peyronie’s often describe hearing a loud ‘crack’, followed by pain and bruising, although in many cases you might not remember any injury happening. Usually this type of injury leads to swelling which becomes red and hot, and will heal by itself within a year. Sometimes, recovery takes longer, and scarring can happen.
I will say though that I experience NO pain whatsoever, both when not erect and when erect and all penis functions are 100% normal. It's really only the lumps (which are not even visible) which are the symptoms. My penis also does have a bend in it, which has been present all my life but has posed no complications due to this (neither when going to the loo or nor when having sex).
This condition isn't also widely known with no firm answer as to what causes it - treatments also limited on the NHS. I haven't yet seen a GP as I need to call on the day for appointments so getting one is not easy but I am guessing I will be referred on to a more specialised dept.
I am not even sure if this is worth progressing if its posing me no problems....?
