Help

Patient: I’ve been getting these itchy blister like bumps lately and they always seem to disappear and reappear on their own after a while and this has been happening since last year around April . Now I’ve developed lower back and lower left abdominal pain and swollen gland in the left side of my neck and headache pain this week but it all stopped yesterday and now the bumps are reappearing again and my back is breaking out. What STI do you think this could be or is it one? Help please
