I am experiencing low back pain and overall weakness upon standing/walking that is interfering with my ability to shop for groceries, bath and dress self, prepare meals etc. ..as I am in danger of collapsing on the floor and am forced to sit down after only a minute or two. I am 52 years old and struggling with CFS/ME, FMS, and mild COPD. I am being treated for FMS with Lyrica x 4 weeks; COPD with Combivent. Thoughts and/or suggestions are welcome.
