whenever you have significant physical trauma that results in an injury inflammation will occur on the site where the most impact occurred. when inflammation happens some people will develop a low grade (99. 9 oral temperature) fever due to the body working hard to heal itself. sweating could be contributed to such a fever as you are warmer than usual. as for the chest pain it could be associated with his arm being hurt but it depends on how he fell how far he fell and exactly how he landed. he could have injured more than originally thought. for temporary relief he should try r. i. c. e. (rest ice compression elevation) and perhaps some ibuprofen (motrin advil) to reduce swelling/pain/fever. acetaminophine (tylenol) should be fine as well if that works better for him but it doesn't have an anti-inflammatory component like ibuprofen does. ultimately the best thing to do is to see a physician just to be certain that everything is alright and there isn't something more serious occurring. most urgent care facilities will see you same day with or without insurance. emergency departments will as well but they are usually more congested and expensive. i hope this helps. best of luck to you!
can a broken bone or a muscle tear cause a fever? . my father fell a month ago and has been experiencing pain in the arm he fell on. he won't go to a doctor because he does not have insurance. just this week he said he had a sweating spell and has been feeling "under the weather" for a few days. no other symptoms then he thinks he had a fever and even muscles in chest ache. so i am not sure if he just caught some virus or if maybe something from his fell is trying to tell his body.
