I am 22 years old and around 6 months ago I found a small lump under the skin on my penis. The lump is pea sized, located just under the head on my penis, the lump is slightly movable and there is no pain present. I have been to my doctors and they told me not to worry, but i was not convinced - I felt as if the appointment was rushed and they parred me off. I have noticed that the lump now has changed and I can feel things that feel like veins connected to the lump. The lump seems to become larger and much harder when I apply pressure, and when erect the lump sometimes feels rock solid but other times is extremely small (is still there). There is no pain, swelling and redness.
Could anybody give me some insight into what it is? What is the best thing to do? If it is worth seeing my doctors again?
Thanks
