Hi there! Definitely pricking those bumps is of no help. Going to the doctor is a good decision. It's hard to stop yourself from scratching those itchy bumps but do control yourself. Washing your body with cool washcloths can decrease itching sensation. This was also thought to be an essential intervention in an article from Nursing Standard, which stated that implementation of cold or cool washcloths would soothe the patient’s skin and alleviate the itch momentarily. Good luck and see a doctor! :)
