Hi, just wondering if anyone knows what can help my son. He is 13 y/o and has a compression fracture from football in the the head of the humerus. This is day #6 and for 3 days the muscle spasms have been terrible. He is in a sling and swathe. Taking 400mg ibuprofen every 4 hours and tylenol #3 about every 6 hours. The dr said no heat to the shoulder area bc of the break, only ice. We did put heat to his chest area and neck but did not have any results. The dr said that muscle relaxers would not help this type of pain. I am confused??? Is it that he has the spasms due to being used to a vigorous 2 1/2 hour workout everyday and now he is immobilized by it? I know that lactic acid can build up by this, but this seems extreme. Any help would be so appreciated and thank you in advance.
