Hey you guys, i have a concern and to save some money before going to see a doctor i wanted to check on here to see has anyone ever had this problem or have experienced this.

Just a quick explanation: it use to happen every once in a while (unless i just didn’t notice it). i tend to get these marks on my body, they are very small. I’ll get a burning sensation for a little while (i guess while it’s appearing) then before i know it... i have this mark on my body that resembles a mole but it is not. After a few weeks have passed i can scratch it off. I don’t get it, i don’t understand & i really just want to know what it is. Also, they come in different shapes and sizes. I’m currently in college, biology major, so i know and do understand that your body has ways of letting you know things are going on with your body. I’ve googled but just couldn’t find anything like this. If anyone knows anything.. please let me know. Pictures are included below.
