Could you please explain the reason for pain in my penis?

Hi doctor

About 11 weeks ago, I had unprotected sex when drunk. I have been tested and all clear. But, from the next day I had throbbing, dull ache on the penis. Then after two weeks, I realized a vein under my shaft on the right side had become inflamed. I can no longer masturbate or touch it without feeling intense pain. It hurts and does not feel right since the incident. In the mornings, I feel a dull ache as soon as I wake up. I am afraid that I will never be able to have sex or masturbate again as it is so much bigger than the other side. It does not match up its kind of look. I have read about Mondor's disease and varicose veins. I was freaked out, because there is no cure for varicose veins. Could my penis really be damaged forever? I am so lost and upset. Can give me some advice based on the pictures? Thank you.

Thank you doctor,

If I masturbate or touch it sexually, it hurts for weeks. I am so scared and at the point of doing something stupid I am so worried. It has been going on for three months and I have no idea when it will end. What to do to make the vein normal again? Could you tell me why does it hurt so much in the morning for the first one hour when I wake up? Is this condition the same as inflamed lymph channels? Could you tell me what surgery would involve and how I would go about getting it? I am slowly going insane with worry.
