I accidentally pulled the skin on the Dorsal side of my semi-erect penis back too far while showering, and immediately felt a sharp pain around what I later learned to be the "vulnerable area" of the penis, where the nerves and dorsal vein runs. After that, I noticed a lump exactly where I felt the pain, and the dorsal vein is displaced to the right, ending to the right of the lump. It seems almost like the vein and the lump are attached. Also, the veins running out of this area were are more prominent than they were before. This happened 5 months ago, and I don't really feel much pain anymore, but sometimes that lump-area hurts after I ejaculate. Also, there is a tendon-like line which runs from the Base to the Glans, to the right of the Dorsal vein and lump, which seems to have its complement on the other side (these could be nerves). All of this amounts to quite a serious change to the physiology and appearance of my penis, and I'm frightened of hurting it more, but maybe I'm just being paranoid. I have no problems maintaining an erection, but since the vein is so prominent and displaced I worry.
Do you think this Dorsal vein/lump problem is serious?
Could it get worse?
Thank you very much for your help, I hope my question isn't too long-winded.
