It seems simple and I say it a lot: Follow your doctor’s advice. If after an auto accident you are told to not pick up certain things that way 15 or more pounds, then don’t do it. No matter what some may say, everyone wants the victims of car accidents to get better fast. You pay the doctor big money to advise you how to get better fast.
Your doctors know what they are doing. Follow their advice. If you are on work restrictions then follow them. If you are to “take it easy” then do it. There are always going to be exceptions, and I understand that. But, after an auto accident and before you decide to go do something ask yourself what your physician would say.
