FYI, everyone who gets transient lymphangiectasis or similar sclerosing lymph channel thinks they have a thrombotic blood vessel. They worry that oxygen is not getting to some area. It feels like a thick paste is in there and perhaps it has become a series of bumps rather than a smooth tube (or not).
The doctors say that this lymph channel blockage is "self limiting" because it tends to go away by itself (in 4-6 weeks) rather than get worse. But it doesn't always go away. Be careful if you have the bright idea of putting a steroid cream on it as steroid creams can thin the skin that's already thin.
Standard advice is to reduce physical disturbance of the area (refrain from the fun stuff) but the alternative advice is to manipulate it to break it up, especially from the end of the channel near the base (away from the glans) in order to release bits downstream. Perhaps also to use a vacuum pump briefly to cause expansion of the vessel such that it exceeds the diameter of the blockage (whoosh). Too much pump can CAUSE the blockage so beware.
After 8 months you've probably followed the standard advice a few times by accident.
You can get rid of them years later so the time passage is annoying but not a setback.
