My husband this afternoon started having a sudden strong pain in most of his joints. Ankles, wrists, knees, elbows, shoulders. No fever, no symptoms of flu. No headache. Just the strong joint pain that he has ever experience before. He has taken Advil, but its not getting any better. Could you give us some sort of an idea what this could be?? He is 63 years old. He is a 20 year Chron's patient. Thank you......Should we go to the ER???
