I am concerned about my mother in law, and she is in pretty good health for her age, she takes meds for blood pressure, and she watches what she is for minor gall bladder issues, but other than that she is pretty good, but, she constantly complains that her legs from knee down ache. We tried bio freeze, she takes Tylenol but it s to the point she sometimes just can t handle it. Doctors are telling her there is nothing g wrong. I was thinking to try her on ibuprofen instead of Tylenol, and was hoping for anything else, like a cream or something that would help her. I was wondering if she has maybe restless leg syndrome.
