Peter,
Go see your doctor!
I just cannot imagine that your scrotom is being pinched in a way that could cause blood blisters and you not being aware of or feeling the pinching. How would you soak your scrotom in Epsom salt??
Do you wear tight pants or underwear?
Go see your doctor...PLEASE.
Hope you get relief and answers! Much luck to you.

Hello,
From the symptoms it can be blood blisters or angiokeratomas. Blood blister is a type of blister that forms when subdermal tissues and blood vessels are damaged without piercing the skin. Apply cold compresses, soak the blister in Epsom salt try to avoid its rupture. If the blister breaks, quickly rinse the area and apply an antiseptic such as neosporin. It is not recommended to break a blister because it may often lead to infection.
If the symptoms worsen or persist then please consult a dermatologist.
I hope it helps. Take care and regards.
