Seizures and indomethacin?

17 year old son was precribed 75mg of indomethacin 2 times a day for 10 days and then once a day for 2 weeks for a shoulder injury (he is an elite competitive swimmer). He had odd breathing and leg kicking episodes three times before we recognized these episodes were seizure-like. Meds were stopped 2/9 when we realized a problem and medical attention was sought. 4 months later our son continues to have seizures and he was gone through numerous tests, seen specialists, and been hospitalized for additional monitoring! Side effects list rare side effect may be seizures in individuals who may have had a predisposition to seizures. Our son never had anything of the like prior to this medicine. Seeking other similar experiences. We are seeking proper medical care not who to blame. Simiar experinces will help our son's medical team.
