What type of bite Spider or Insect? Any cause for concern on 10 year old daughter?

Any help determining what type of bites these are about 1 inch away from each other? The one bite has a 1" ring around it and is darker in color like a bruise.

Any cause for concern or should we see a doctor, it's a 10 year old who got these bites while we are in Myrtle Beach camping.

Here is link to the picture:









Thanks for your help from concerned parents! Doesn't look to bad right now and child isn't acting or complaining any different. Just hurts when you touch/apply pressure to it. Tweet
