Silly question I know. My pains are bad today, but also my back is hurting from where I fell a couple of weeks ago. I haven't taken any Voltarol or Ibuprofen tablets today, but put some Ibuleve max on my back about 5 hours ago. Can I put it on the other painful areas - feet,ankles,shins,arms,necka dn hands? Or is that going to be too big an area? and I would be better off taking 2 tablets?
