Yesterday i went hiking through a forest and throughout my time their and when i got home i never felt a bite or any kind of pain. As i was getting ready for bed i noticed a red circle in the middle of my pelvis area and i could feel a bump under my skin. I thought it it was a pimple and i tired popping it but that didnt work. When i woke up the next morning the red dot was still there and right underneath it there was what looked like to be a circle of dry blood underneath my skin (maybe from trying to pop it). It doesnt itch, theres no pain, if it ever does hurt itf from my pants rubbing against it. My pelvis area has some swelling but not a crazy amount. Do you think is an insect bite or something else? Should i go to the doctor right away or wait for a day or two to see if it goes away?
