I fell down on my right side, and feel lots of pain. Hard time taking big breath, painful when i cough, or try to push stool. I fell two days ago. I have been taking Motrin over the counter,and it helps a little, not much. I have some Robaxin , which they tell me is stronger for the pain. I need to block the pain so I can move easier and heal. I have to be able to lift a minimum of 40 lb. for my job, and I can not right no with the pain. I m 63 years old, and very active. Is there some other medication I could take that is strong like Robaxin.
