Your mode of injury and the nature of your pain ( radiating , burning ) gives some insight into a possible disc/ nerve compression issue . I would suggest you seek medical examination from an orthopaedic , who might also want to investigate in the form of an MRI and perhaps recommend physiotherapy , which is generally done in such cases. In spite of you being in good shape , particular attention may also be required with your routine postural habits , the type of exercises you do and specifically the core muscle strength, all of which the physiotherapist will assess and guide likewise. Even if your pain subsides , with rest and medicines, issues pertaining to muscle strength and ergonomics will need to be sorted out to prevent future similar occurrences.
