The dear doctor! I had a small tumescence at once behind a head of a member (0, 3 on 1, 5 see) which increases noticeably or is noticeably enlarged at each erection and then some hours do not fall down. Before it or this was not. Prompt, please, what is it can be and whether it is necessary to struggle with it or this. In advance thanks.

Phlebitis of superficial veins. But it is not assured or confident. It is better to see a doctor. I think, that is quite reperable.
