I'm in so much pain in my 2nd trimester due to my sciatic nerve. I could barely walk in the store, I was shaking from the pain and almost collapsing. I got stuck on my couch because trying to roll over or sit up sent excruciating pain up my back and down my leg. I just want to sob when I'm awake. Tylenol hardly helps, I've tried stretching, warm baths, laying on the unaffected side......I'm at my wits end with this pain.

Please, any advice or exercises to try would be much appreciated.
