little bumps around butthole

Hii,,
So ive had to go through the herpes scare but got tested and test was negative.
The bumps are slightly raised no puss and not hard.. looks like a pimple minus the white head..
Theyve beem there for 4 weeks now.. i antibiotic cream (has steroids and cortozone) they heal but others appear.. like 2 would heal and then id get another one.. i don't understand what this is.
