I was diagnosed with stage 4 small cell carcinoma in June of this year. I also have an auto-immune syndrome, called Lambert-Eaton myasthenic syndrome, which attacks muscle, tendons and joints. It is hard to walk, get up from a chair, driving, bathing, etc. It gets a little better with chemo and radiation, but it's still there. I have 3 weeks of radiation left, then a little break, then 3 more weeks of radiation of the brain that is preventive. I hope to help others cope with this. I didn't have anyone, so I'd like to be of help to you.
