I'm recovering from what appears to be a "bed bug cyst" and it wont heal! I've continued to let it drain but it wont go away. What can I do?

BED BUG CYST? How long has it been there? From what you are saying, it doesn't sound like a "bedbug cyst." never heard of a "bedbug cyst." see your doctor if it has been there for awhile, especially since it has been draining.
See a Doc. You should really see a doctor if it is not healing. It could be infected.
