Small Rubbery Lumps Under Skin on Scrotum?

many small flesh colored bumps on my testicles. Some are single some are in clusters. I visited three separate doctors and none of them were sure what these bumps were so I have been forwarded to a dermatologist. The only problem is my appointment isnt for over a month. These bumps when squeezed reveal a small rubbery lump underneath the skin. When popped the lump comes right out and it starts to bleed.. Was hoping to get some sort of clarification before my appointment. Thanks
