Hello from JA
First, you need to see a urologist.
Oddly enough, scarring can develop in the penis without trauma...called pyronie's disease.
The urologist can determine if you have an early case of this and treat it correctly.
Circulation problems can be ruled out with ultrasound.
Pain here can also come from prostate inflammation and this can be hard to diagnose...so again, a urologist diagnoses this daily. Rectal exam and then urinalysis are needed.
As long as you are urinating OK and get erections OK, there is no emergency here, but you shoudl be seen by the specialist soon.
OK. If you have further questions or details, use reply to expert.
Otherwise please choose a positive rating . But, still come back if you need to…think of something later, etc. Bonuses are appreciated.
