Just like you, I also had those bumps in my thigh, jaw and recently
in my
neck.
In my
neck, i tried hot compress and it gets smaller... Those found
in my thigh and jaw, they stayed there for years now. They didn't give me pain. The doctors, told me nothing to worry about. I was just told to increase my water intake.
For your peace of mind, better consult an expert on the field. A dermatologist. EENT, or any physician who can diagnose you better.
Regards.
