Going on 10 months of mono with severe shortness of breath - would love some advice!

I am new to the group and so glad I found it. Last year I was just finishing up with my 4th surgery after thyroid cancer surgery and treatment (also have paralyzed vocal cords as a complication from the surgery which does limit my breathing from the vocal cords paralyzed closed). Had the final surgery June 09 and after physical and speech therapy returned to work in November - felt wonderful. I was working out, working my 10-12 hour days. In January 2010 I started to feel so tired I could hardly get out of bed, but I did. Then I started having chest pains on left side. So I drove myself to ER. Heart was fine. Kept having pains, shortness of breath, exhaustion, sickest I had ever been. Finally went to doc and asked to be tested for valley fever (I live in southwest) and also mono. She said a bit surprised oh you have mono and as I was in her office with my head laying on the side of her counter because I was so weak she asked what was on my neck, well I had sores - blisters all over my neck and chest. Shingles was her diagnosis. Anyhow after 10 months I still can't breath - feel like I am in a sauna - but only feels like the left lung. I have had every scope, CT, MRI, test there is to have. I asked doc if shingles/mono could damage a nerve that controls the left diaphragm (actually asked two docs). They said Hmmmm... good question. Has anyone ever heard of such a thing? By the way, I just had another surgery last month because one specialist thought my paralyzed cords had moved over to far midline and was closing to much of my airway so had surgery to move over a bit. It helped a bit in the throat area but the lung still has the pressure and sensation of fullness. Any input or ideas would be greatly appreciated. Thanks so much and I am so sorry there are so many of you out there going through this but I do find comfort knowing that I am not crazy (I was starting to feel I might be but hearing your stories I now know I am not alone). Thank you all!
