Weird surgery recovery

so i just had knee surgery a week ago, before surgery i could go hours without eating. never ate when bored, and ate fairly healthy when i had access to healthy foods. after waking up from the knee surgery with the anesthetics still in my system i noticed my whole body felt tingly, my mouth felt so dry ( i drank like ten cups of water within an hour) since coming home from the surgery i noticed that i have had to go to the bathroom a lot more than normal, but also my appetite has increased drastically. to the point where i almost always feel hungry, and if i try to ignore the hunger i start to feel tired and lathargic but after i eat i feel a lot better. and i am over obsessively craving meat for the last few days. meat and other nuts. my leg still gets numb even with me trying to move it as much as i can and do my exercises. has these symptoms happeed to anyone else after surgery? what did they try to do to try to control those synptoms? ive had surgery before, but never reacted like this.
