My elderly mother (over 90) has appointments at two London hospitals in the next week. One is a heart appointment, the other an eye appointment. The eye appointment is important because if she does not get her regular injection, she will lose her sight. The heart appointment is a check-up; she was given medication at the last appointment to take if she gets pain. She had one episode of pain in the past week, but took the medication and felt better. In the current circumstances, I feel nervous about her going to either appointment? Which should she go to--or both?
