Hi, I'm late to the conversation but am so glad you are doing better. It has been a heavy snake season here in north central Arkansas this year as well. I would be willing to bet it is a copperhead bite too. I found a small copperhead curled up on top of a decorative stake in a pot, inches from my nose. In a two week period here we have dispatched 3 copperheads and a 4' timber rattler in and around my potted plants. This is a first, we have occasionally had copperheads near the house, but never this many, and never rattlers. Everyone please be careful and stay aware of your surroundings.
