My mother is 91 years old. She had off and on urinary infection, which is under control now. Probably because of urinary infection, her one leg is swollen and become heavy. She cannot walk independently and need support of family members to move around. Her food intake is ok now.The problem now is that she complains of vomiting tendency every now and then and put her fingers in the throat to force vomit. But no vomiting takes place. When we object, she start crying. She speaks very sensibly. We don’t understand what needs to be done to make her confortable and at ease. Seek your valuable recommendations.
