Hey KV...No doctor or nurse, but PhD in constipation (pain has debilitated)
A few things...
Warm enema w/some lubricant in solution/Massage abdomen gently during. It may take several attempts. Assume a muslim prayer position.
If she's not throwing up, Magnesium Citrate liquid. I'm given this along with Dulcolax pills when I'm blocked. I also take larger doses for colon prep. It's citrus flavored. Pour over crushed ice and sip 1/2 a bottle. My nurse saved my life with this cocktail in the hospital.
Miralax I don't think would help, because it takes a while at start-up.
Can she swallow LINZESS? It's capsule prescription. It works like Miralax, drawing water into hard, dry stool. It's a miracle, too.
Bless her sweet heart. I know this misery (sans PC) as only those who have experienced it. Oh, I weep for her pain.
PLEASE ASK for LINZESS or one of the other new meds for OIC.
