My boyfriend has stage 4 lung with met to many bone areas. He is treated with chemo once a month for 7 hours, His chemo is Avastin carboplatin and taxol..He had his last chemo Feb 23. He also had 10 rad to neck and 10 to shoulder in last 6 weeks. Problem is he seems way to weak now, Having a lot of trouble getting around. I forgot to mention he also had an infusion of zometa 3 weeks ago. The question I am asking has anyone ever continued to be so run down from treatments that they could not get around even 2 months after..
