I am training for a 270 mile-3 day bike ride in September, but last week I injured my coccyx when I slipped onto my road bike seat. I am a 53 years old female, weigh 135lbs and 5'3" in excellent health and need to get back on the bike asap. I rode 28 miles 2 days ago and had no pain during the ride, however yesterday the pain returned it was about a 5 on a 1-10 scale. I am fine unless I am sitting on a firm surface. I have iced it and taken ibuprofen with good results. This ride is very important to me, please advise.
