My mom just got sciatica for the first time

She is in crippling pain, unable to walk, and crying in pain every night. She went to the er yesterday and they gave her two shots and pain medicine and nothing is really working. My mom has never had this pain before and it’s from laying on an uncomfortable surface a couple nights next to our puppy so the puppy calmed down. My mom works 80 hour weeks too so it’s been hard to see her have to do work while in such pain.

When should this get better? It’s been probably a week and I’ve had to step up to take care of the household. Oh we’ve also used heating pads, lidocaine, and tens unit. Is there anything else I can do to reduce her pain? I would really appreciate some advice because I hate to see her in such excruciating pain.

Thanks in advance
