This isn't really a school problem but 10 points.

my mom has excruciating back pain she can barely like bend down to to reach stuff it hurts here randomly like it feels like they are stabbing her back..
what could this someone plzz .

I'm not a doctor, but stabbing pain in the back is pretty serious and she should go to the doctor asap

Its possible she has a strain in one of her muscles. Common causes of sprain and strain include:
Lifting a heavy object, or twisting the spine while liftingSudden movements that place too much stress on the low back, such as a fallPoor posture over timeSports injuries, especially in sports that involve twisting or large forces of impact

Breastfeeding should last for 12 months.
