One step forward (NEW CHAIR), one step back (SHINGLES)

I got some good news, then a week later some bad news.
The good news–I finally got me electric wheelchair/scooter, or whatever you want to call it. It took over TWO YEARS of red-tape, where first my insurance company delclined it, and my team of doctors had to write letters, and they did MRI’s of my arms, showing declining usage of my arms. Finally after over one year, my insurance company decided they would cover it. But it turned out they only cover 50%, which left $2600.00 for me to cover…NOT!!! So, then we had to start all over again, with my secondary insurance, Medi-Cal, to pay for the rest of the 50%. So, after another year went by, I FINALLY GOT MY CHAIR. Oh, and it couldn’t have come sooner, since it has been so difficult on my arms, pushing the manual wheelchair.
I have read some of the threads on people who have the chairs.

Then the bad news…For about a week, my upper diaphragm felt as if someone was standing on my chest–very painful, with sometime a stabbing pain. Then, last week, a rash started on my back. My mate insisted I go to my Primary Care Doctor, which he took me right away thinking it was something with my heart. He saw me two days after the rash started, luckily. He took one look at the rash, and told me I had SHINGLES.
GREAT–just what I needed on top of everything else. He immediately put me on an anti-viral med, Acyclovir, to be taken 5 times daily. And, since I have a poor prognosis with the CIDP, was willing to write a script for any kind of pain pill I wanted, but told him the Vicodin was working okay, (I have to take it every 4 hours since the shingles are very painful).
Today is a week since the rash started. I guess the pills are working, since it slowed the spread of the rash. Luckily, I don’t have much feeling on the skin from the CIDP, so it isn’t itchy for me. It is just very painful in the morning when I get up, and don’t have any pain pills in me yet.
My doctor said that anyone who gets the chicken pox, has it lying dormant in their body. Because my immune system is so low due to the Chemotherapy I am on, it came out of it’s dormancy, and came out as shingles. He told me my body is open to any kind of oportunistic disease, with my auto-immune system being down.
Has anyone else here had the shingles? How long did they last for?
My doctor gave me the pills for 10days. From what I have read, it can last 2 weeks to over a month, if not longer. Should I be getting more pills?
Let me know-it will help….THANX, KEDASO
