My mother was bowling (82 yrs old) and while stepping backwards she lost balance and fell backwards and landed on her butt. She felt immediate pain in her lower mid back (none on her tailbone area--just back). She could not get up without help and could barely walk  to the car. Her lower back hurts and she is in a lot of pain (only when she moves) sitting in a recliner and refuses to go for X-rays.   she said when she walked the top of her legs hurt but there is no numbness or shooting pain. We put ice pack on it for about 30 minutes. This happened about an hour ago.  What does it sound like to you. She swears nothing is broken but Im fearing the worse the longer she waits to go to hospital
In my opinion need to consult or tho doctor who can find the damage caused by fall by investigating through X-ray it can be muscle tear swelling nerve pressure or edema of discs or fractures. Immediately you can use muscle rel extant and anti inflammatory tabs along with these medicines you can use local muscle rel extant ointment slow protein diet antacids as acidity increases back pain plenty of water rest till you get diagnosis
