I’d like to give my two cents if I may.
I, like many, have had quite a bit of trouble with lymph (for sake of simplification) right below the glans of my penis on the left had side. It would normally appear after an intense pumping session or a very intense session of masturbation. In order for me to clear what appeared to be a “string of pearls” (as many have described it) I would heat up a sock with rice and work it out exactly as it has been described. However, 4 months ago something much different happened to me. Instead of having the normal/lumpy/pearly feeling it was exactly the same, I could feel the lymph vessels exactly the same as I always had been able to, but with no lumps, all while being inflamed. In addition to being greatly inflamed, it also was sore as if it were bruised.
After one month of it not going away, I decided to go to a urologist (I have good insurance.. So its free) and he told me it was a growth that immediately had to be removed otherwise it would continue to cause me pain. Not really believing what he said, I went to another urologist. This one told me that my veins were inflamed (which seemed weird to me since it was the same exact vessel that had always bothered me when I would get the lump/pearl blockage) but I took his word for it. He prescribed me a steroid cream (that is commonly used for bruises and varicose vein problems here) and told me in 3 weeks it would all be better.
Fast forward three weeks, no change. I go back and he says that it just takes time and that I should refrain from any sort of physical activity and avoid erections at all cost. Again, believing what he thought, I follow his advice. No changes.
I go to two more urologists during this time. One gave me the same advice as the previous, however the last one was convinced that it was not a vein, that it was a part of my lymphatics and then recommended that I do intense exercise and rebounding to get my lymph moving. From this moment it had now been about 3 months with a swollen penis, I was so desperate to have anything fix it because it was causing a lot of psychological stress in addition to the small amount of physical pain that I had. I took a piece of bandage and tightly wrapped it around the part of my penis where the swollen vessel was and, following the advice of another poster (I apologise for not knowing his name) pumped my penis with the bandage. After about 20 minutes of intense pumping I left the tightly wrapped bandage around my penis for the night and the next morning was the first time I saw any change. I continued this for about three days until it had almost disappeared.
To this day I haven’t been able to get rid of the vessel like I used to, I can still kind of tell that it is there when it is flaccid and I can definitely tell it is there when it is hard, but it no longer causes me pain.
I personally think that I didn’t have a blockage like many have mentioned, but that my lymph vessel became aggravated and inflamed which is why no amount of “stripping” did any good.
