Ma has lung cancer and has gone through kimo and radiation, lots of it. Now that the treatment is over and her hair is growing in she cant walk, one leg has no feeling and the other just doesn’t work, docs have no clue why, she grows weaker every day. Anyone hear of such a thing?

I strongly suggest that you mom do a MRT on her brain to see if there's mets to brain. This happened to my mom. Best wishes!
