Hello, I recently got 2 spider bites, I don t know the type of spider. Two bites are extremely swollen and blistered open, but then I have 5 or 6 other large, hard under the skin bumps right around them. All located in my right armpit, and one goofball sized under the skin bump also complete opposite from the bites but still so severe? I want to drain the bumps but wasn t sure if it was lymph nodes and if that s not okay?
