i felt a little pain underneath at the base of my penis when i lie down face up. Its been a week now and sometimes i get strange vibration too. There s no pain when lie down other postion, even sitting but walking sometimes. No pain during urinating or erection. Ejaculation not check yet but my last one before this happened was ok. I also had gone through a major cervical Op in April and now having hospitalisation leave at home. Hope you could enligten me on this. Thank you.
