Thanks for your query.
You need to get an X-ray of the area done to detect any such injury. An MRI scan is recommended to find out a soft tissue
abnormality or a tendon injury
make elbow fixation by elastic bandage
take pain killer medication like ibuprophen
after that take physical therapy
sessions for elbow
ice pack if there is swelling or hot pack
I do hope that you have found something helpful and I will be glad to answer any further query.
