Yes it can. I'm currently having chest pains from sleeping the wrong way. Be sure to take ibuprofen & try to relax as much as possible. You may find it difficult to take deep breaths but don't worry. Just let the pain go away by itself & try to sleep on your back at night to give your chest a rest from the pain
