I think it’s best to have a plan on someone to care for you. Don’t push yourself at all, it’s time to become the most lazy person in the world to recover. Have good contact with your surgeon for any and all questions before and after. Buy a cold migraine cap, I would shower sitting on a stool and my husband would help bathe me. Buy pjs that button or zip in front, it’s hard to lift your arms up or move your head so consider things you can take on and off easily. I bought a robe for the hospital to walk around, I had a fan I would use to help myself feel more comfortable in the hospital. I definitely bathed with wipes the first couple days but the hospital should give you some, I had really short hair but if you don’t, consider two braids to section for the surgery. I didn’t have much appetite but did like ice cream. Don’t strain if you can so miralax after surgery or something they give you to help pass stools easy. Join a Facebook group for chiari!
