I'm only 22, but I'm pretty sure I have hemorrhoids because for the past several days I've been dealing with rectal pain. Are there several different type of hemorrhoids?
There are not different types of hemorrhoids, only hemorrhoids in different locations, such as internal or external. The former should not cause pain; the latter only cause pain when they get clotted (thrombosed).
Internal hemorrhoids
External hemorrhoids
Intero-external hemorrhoids
