NHS -
To get rid of groin pain fast, use the RICE method (Rest, Ice, Compression, Elevation) for acute injuries, take over-the-counter anti-inflammatories like ibuprofen if you don't have contraindications, and after a couple of days, you can introduce gentle range-of-motion exercises and heat to promote healing.
Rest the injured area and avoid activities that cause pain.
U could next week contact the MRI Dept and ask the question. Have U had a report from there, a copy may have gone to your GP too. We have an on-line triage system at our Surgery which works well, either with a phone discussion or face2face appt.
