Crippling sciatica pain 😭😭

It’s INTENSE please help what can I do ?

I can’t take a bath bc it’s so bad I can’t get in or out of the tub. Showering is actually terrifying too lately I’m afraid my leg is going to give way

I can’t even lift my toddler anymore bc when I have I’ve almost dropped him.

I already wear a support belt during the day but by night time the pain is AWFUL. I cry getting up to pee at night it takes all my strength to fight through the pain getting out of bed each time. Sometimes it’s so unbearable I just freeze awhile trying to breathe through it.

I already sleep with a u shaped pregnancy pillow. I’m currently bouncing on a yoga ball

Help me I’m desperate.
