Should I Seek Medical Attention For Sharp Pain After Lower Back Injury?
Probably vertebral disc issue
Detailed Answer:
Hi and welcome.
It sounds to me like disc herniation issue or lumbago which is related to nerve roots around the spine. This is common especially after sudden movement or inappropriate exercise. In most cases this may be unpleasant but usually is self-limiting.
You need to rest strictly, take nonsteroid painkillers (eg. Acetaminophen/Tylenol 650mg thrice daily after some food). It should improve in next few days.
If however, you experience legs numbness or weakness or you can't control bowel movements or urination then you should see a doctor immediately. Otherwise, it can be treated at home, and if pain becomes significant, you should see GP to have stronger painkiller shot.
Wish you good health.
