Hi, thanks for writing to HCM.
An xray of the pelvis is necessary to rule out any bony injury
to the ischial tuberosity, coccyx
The gluteal muscles
might have strained due to fall.
Follow these general guidelines -
* Rest to the local part and don't involve in activities that causes more strain
* Ice packing once in every 2 hours to reduce the pain
* Use muscle relaxant
gel as local application
* Moist heat fomentation to relax the taut muscles
medications like Advil or Aleve as needed
If your pain is not resolving with the above measures, consult an orthopedic surgeon for further workup and management.
Hope this information is helpful. Good day
