Hi,
Welcome to Health Care Magic, and thanks for posting your query.
I understand your concern.
If you say there is a swelling and a
bruise, its better to get evaluated than to neglect it. Though he is able to move his hand , since there is a little pain in doing so, i suggest you to Get a X-ray done of the elbow which is hurt.
Do consult an orthoepedician who will be able to comment on the Xray for you and advice accordingly. Probably your son will have to wear an arm sling for few days, or if its a
fracture the doctor might put a cast to fix it.
For pain give him
Ibuprofen 100 mg twice daily after food, do not
massage the area with any
analgesic ointments/gel. if you need to apply them then gently just apply it without rubbing it all over.
Hope this helps, and answers your query satisfactorily.
Wishing him a speedy recovery, good health.
Take care,
Regards.
