Last night I propped my fort door open while cooking dinner to help with the smoky like air. After a while I noticed this on her upper right leg. It’s gotten a little brighter in color and is bumpy feeling. My daughter is slightly itchy around it. I’m not sure if it’s a spider bite, mosquito or flea bite from our cats. Also to add this is the area or super close to the area she got her shots on back on February 1st.
