I Have Either A Rash Or Lots Of Bug Bites

I have either a rash or lots of bug bites all over my body. I have had this condition for 10 days but it is getting better. This rash or these bug bites are very itchy and I itch so much that I start to bleed and now have scabs. My doctor says this is a rash caused by stress but I don't feel that stressed. Should I see a dermatologist or since the condition seems to be improving should I just wait and see if it completely heals.
