Hello: I've just found this website and am so where you are! I am alot older than you, but have been experiencing similar symptoms and going to doctors for 6 months trying to find out my problem.
I too am suffering from shingles pain on my right side and thru to my back. First let me say, hang in there. It's really important to have friends and family around. I have felt many times like I just can't make it, and then my sister helps turn me around. I went from being extremely active to nothing, actually laying in bed for over 4 months. I really do know how you feel.
I have just recently found a good pain management center, who "diagnosed" me with shingles, although 6 other doctors said I couldn't possibly have it because I had no major breakout. I actually did have a breakout that was like little pimples and kept saying I thought that's what I had, but NO ONE believed me. I also almost had my gallbladder out until I really listened to what a doctor said and realized that many times they kind of put you in a "box", fitting you into their profile. Don't let anyone do that to you.
Currently I am taking nortriptyline, which has helped greatly with the pain and they want me to also take Cymbalta. I'm working toward it. I am not much for meds if I don't have to. But when you feel horrible, you'll try just about anything!
I would say to try to find a pain management center at a larger hospital in your city. The people you meet make alot of difference and in my case, this last group has been great. They also have a psychologist that I am going to see for my depression. Although my pain is getting better, I have had huge issues with my whole "healthcare" experience. I think just being heard will be great for me. Also, there is a website that may help you "healthjourneys.com". They publish all kinds of CDs on guided imagery and things like that for relaxation and pain. The one I like the best is by Belleruth Naparstek Ease Pain. It has helped me with my mental journery thru all of this.
I wanted to reach out to you because I know the level of frustration you probably have, which really does lead to hopelessness and then depression. It's very hard and you are very young. I'll tell you, I may have some perspective in life, but I don't feel any older than you. When you are venerable and hurting, you need someone to help. Also, reevaluate what's going on in your life. I was under trememdous stress for over 4 years and I know that's what did it. I can't do that again. Even younger people have tons of stress, so it's something to think about.
I hope that helps. Take care and take a deep breathe...it really helps.
