Wouldn't you just make a milkshake (or smoothie bowl) from Oat Milk, ice and perhaps a couple of strawberries and nurse that over an hour or so? and then follow with an icepack from the (3rd) freezer for when the pain comes back?
It's what I did when I felt like I'd been twatted round the chops after the arthritis meds meant I developed a 5 inch abscess in my jaw and the emergency dentist (on a Sunday, no less) opened up one half of my face to clean it out before I developed Sepsis, rather than just pain, dizziness and a rapid heartrate to go with the raging temperature. You know, as you do, what with it not being anywhere near as bad as radio/chemotherapy side effects?
