Is thrombotic external hemorrhoids hard or soft?

Thrombotic external hemorrhoids are usually hard.

Thrombotic external hemorrhoids are external hemorrhoids, which may be caused by local stasis due to blocked blood flow. After bleeding from damaged veins, blood permeates around and blood clots form under the skin. Thrombotic external hemorrhoids are not caused by varicose veins around the anus. Their texture is different from soft venous masses, and there are induration of different sizes, which are generally harder in texture.

Thrombotic external hemorrhoids manifest as masses outside the anus, usually accompanied by severe pain, and may rupture and bleed.
