It could be an allergic reaction to an insect bite or a traumatic wound. Itchy bumps are almost always allergic in nature however. You can try topical soothing creams (sold at your local pet store) for allergic reactions, and cleaning it with chlorhexidine solution 3% or iodine diluted 50:50 with warm water. This will help some with the inflammation. If it still isn't better after 24-48 hrs then it is best to have your vet take a look at it and potentially give her stronger medications to treat it.

    She could have a flea allergy dermatitis so you should check her thoroughly for fleas. I recommend that you use a monthly flea prevention, like Frontline, NexGard, or Advantage. If you don't see any fleas or flea dirt than she may just have a bacterial skin infection or seasonally allergies. You could bathe her with a medicated dog shampoo to see if that helps. If it continues than she should be examined by a vet for treatment.
