You are not alone. I have been having that same sensation in my right elbow for a couple of weeks now. You don't by chance have fibromyalgia, do you?
It feels wet, it feels like sorta a shower.. but it's wet.
Like a wet sand and feel like a wet and smooth like a heard jelly .
gravel it feels hard wet griity and smmooth
Wet and sweet
The inside crook of your elbow, if you can reach it, is about as soft as lips.
It depends on how serious the doctor feels about your elbow.
it feels like some hair under your armpit. Most of the time for me its sweaty and wet because I do lots of sport.
Wet dirt
It feels soggy in some kinds and absorbed in others
A California Sea Lion's fur feels smooth when it's wet. But when it is dry, it feels like a boxer (the dog breed).
The wet stuff is lymph.
Your right elbow.
