Manipulative physiotherapist, Pain is only a symptom ,not a disease. Manipulative physiotherapist can glide your spinal joints to give you, permanent relief, Drugs give only temporary relief.

In my opinion, it could be a muscle spasm or stiffness due to sudden jerk .

Meet physiotherapist

As per my opinion during such acute situation rest is advisable with a support like L-S belt will help, as of now you can take some muscle relaxant as per Doctors advice, once the pain is less you should go for Active Spinal Muscle strengthening which will help your spine to become stronger. Meanwhile just take some good rest and avoid any prolonged or forceful activities!!
