I had a break out of shingles and its clearing up but now...?

Now it seems that I am getting another big break out. There was only just a small one on my stomach. Now its on the left side which is the same side that the first rash was. Anyways there is a pretty bi compared to the first and it is on my side and stomach as well. Its like a big line. I haven't been to the doctor due to the fact I have no insurance. This isn't my first outbreak of shingles either thats how I know I have it. What could be the cause of it spreading or reoccuring while the other is practically gone? Is it because it went untreated by medication? I have used rash ointment and kept it clean. But I feel like the whole left side is just so itchy and it is driving me crazy. Can anyone help me make a little sense of what is going on?
