Today ii fell in my back and after that i can't lift my leg without feeling pain in my hip and abdomen what can i do?

See doctor: it is possible something is broken so an xray might be useful. An examination first would inform your doctor if you might need a hip xray as well. the back exam might suggest special medication to take for pain and muscle aches. These things are usually much better within 2 weeks. you can usually continue work while you suffer through it.

Get checked: You probably need an Xray and assessment. Please go to the urgent care or emergency room or call 911. Good luck
