Hi, I have an insect bite on my leg that I thought was just a regular bite that will go away, however it has gotten bigger and developed a rash. It can't be an allergy because I just got tested for that and I have no allergies. I went on a hiking trip, so I assume it's a tick bite(?) but im not 100% sure. I went to a walk in clinic and they told me it was just a regular bite that will go away. It has gotten worse since then so I need answers. I have a picture of what it looks like if that helps
