Thanks for writing your query
Based on your description this injury
is called coccygodynia. My advice for you would be-
1. Sitz’s bath- sit in the tub filled with lukewarm water for 10-15 minutes two times daily.
2. Avoid sitting on hard surface and try to sit on one buttock. Avoid jerky rides and take rest.
3. Medication wise you may take Ibuprofen
for few days.Injection depomedrol at the coccyx
also helps.Just discuss with your local doctor.
You may take rest for few days. If the problem persists see your local doctor.
Take care and wish you good health.
