These things need to be looked at by the human eye - nothing we can diagnose via the internet even if we were medical professionals, which most of us are not. We can't tell (and neither can you) if these are moles, an allergic reaction, or something else. You have no idea, and neither do we.
Probably it's nothing deadly, but really, being too scared to go to your doctor is going to hold you back in every way. In 99% of cases, early diagnosis and treatment makes all the difference. Delaying only increases your stress and decreases your treatment options.
Go see your primary care doctor or ask for a referral to a dermatologist. And don't get your skin cancer info from Facebook or anywhere else on the internet! "Dr. Google" is not reliable and just causes you to panic enough to do nothing.
