Today the unit sweeps the snow. I took a shovel and hit it hard. I only feel pain in my lower back. Now I can't bend over. I feel no pain when I stand.

Hello, according to the above situation, the possibility of lumbar muscle sprain or lumbar facet joint dysfunction can not be ruled out, which will lead to low back pain and affect activities.

Guiding opinions:

In this case, you should pay attention to bed rest. Yunnan Baiyao aerosol or safflower oil can be used for local treatment. After 24 hours of injury, electrotherapy should be baked. If the pain is severe, non-steroidal analgesics should be taken orally to relieve muscle spasm. Wear waist protection when walking. I wish you a speedy recovery.
