回复：刚才半蹲干活，把右半侧腰部扭伤，弯腰时很痛和僵硬，请问我

if there is no pain shooting to your leg, it is musculoskeletal pain most likely. it is acute lower back pain.
Treatment: Time + Tylenol + motrin + cold pad (for first 48-72 hours). rest for 24 hours, then you need keep your moving as regular as you can. --- no massage.but you can have some trigger point injection for muscle spasm.
if your pain is going down to the leg, you need to see your doctor. that may related your nerves.
