i just had my surgery 2/16, and was released from hospital 2/17 yesterday . I thought i had a bladder infection...i was going #1 every ten minutes. Pressure on pelvic floor so intense, we went to ER in the middle of the night last night. No bladder infection, thankfully. Just so much pressure only relieaved after using the restroom, but then it returned. Today, Day 3, that problem no longer; but now I have such nausea!! Dry heaved all morning. Trying to drink the New Whey liquid Protein from Walmart mixed in water; a bit of broth and icy Water. When I put a neausea pill side my cheek, it makes me feel more nauseated. Tastes terrible! Help me what I need to know these intial firs few days, if you will ~ !!
