When flaccid, my penis has a painful swelling inside at about the midpoint. It is palpable and similar to a finger where the knuckle is the thicker than the rest of the finger. also my erection is less firm toward the head, past the swelling point. There is no pain/problem with urination, and ejaculation is possible and not painful. While erect, pain comes from bending the penis too much. While flaccid, pain is present whenever the penis is felt. This began a few months ago without an injury that I am aware of. also, it is not the result of overuse.
