My mother has been quite worried that my brother who lives in NJ is on leave from work. I told my mother that there is really nothing to worry about as my brother is not really sick. He just had an episode of a real bad backache when he over-exerted himself while lifting.... a bag of groceries! His backache is intense though as he finds it difficult to sit, stand and walk for long periods. He is better now and it's a good thing he has social security disability insurance. Bro has recovered but he has to take it easy for a while though.
