Tailbone pain after using exercise bike, pain to sit on and tense. No pain any other timeWhats wrong? Treatment

Coccyxdynia. The pain you have in tailbone is called coccyxdynia. This is common in people who sit a lot especially in rode/exercise bikes. It is caused by the continued pressure in that area. One will have to avoid sitting until the pain is relieved, ice, take NSAIDS ie aleve (naproxen) 2 tablets 2x per day with meals. Consider finding an extra cushion for that exercise bike or finding a new bike in the future.
