What could cause pain on the left side of the penis?

Hello doctor,

I am a 28-year-old male, who is 5.7 feet tall and weighs about 135 lbs. I am experiencing pain along the shaft on the left side of my penis. The pain is relatively mild but increases following masturbation. It seems to follow two veins, one parallel to the urethra and the other one that curves over the top. After masturbation, my penis remains sore for several hours. There is no visible discoloration or deformity along the shaft, but the head seems to have twisted slightly toward the right. Erections are normal and do not cause pain, but occasionally I get an hourglass penis shape if I attempt to force a second erection shortly after ejaculating. There is also a red spot at the bottom of my glans. It looks like a burn and feels tender to the touch, which causes mild pain and occasional itching. I have tested negative for all STDs and UTIs. A dermatologist suggested that it is Psoriasis, but it does not look that way to me. There is no peeling involved and no patches on my elbows or knees. I have had the red spot for almost two years, along with the twisting and curvature. The severity of all symptoms has increased significantly since the beginning of the pandemic and staying home. Perhaps stress and lack of exercise have something to do with it. Two years back, a doctor suggested to me that I may have prostatitis following a rectal examination. I experience occasional burning in the prostate, weak stream, and painful urination, especially after consuming junk food or stressing. A liter of water clears those symptoms. I do have redness and peeling around my nose, though, and suffer from seborrheic dermatitis. What can be my issue, thrombosis, Peyronie's, or prostatitis? Are there any home remedies that can alleviate or cure these issues (diet or exercise), or any vitamins or oils should be taken?

Hi doctor,

Thank you for your reply.

Does this look like cancer? Regarding Peyronie's, from what I understand, it is possible to stabilize without causing permanent scarring, in which case it will reverse and resolve within a year. Is there anything I can do to prevent further damage and scarring? Will the curve worsen while it stabilizes? I also hear that stretching, warm water soaks, and consumption of Vitamin E and coffee are all natural treatments to reverse the disease. Supposedly enzymes Serrapeptase, Nattokinase and Seaprose also can break down scar tissue and restore perfect functionality. Is there any validity to these claims? I do not want to consider surgery of any kind.
