OK...I Have Jumped Out Of Airplanes While In The Military,

OK...I have jumped out of airplanes while in the military, got 2 new hips/morphine pump/tenz unit...so I have nerve damage and other issues...but, after my last hip surgery my body has been doing strange things like retaining water in the legs ...the biggest strange thing is every month for about 3-4 days my body starts sweating like I am going through withdraws, I cannot eat, cannot drink, I can just lay in bed falling in and out of sleep until I go to the ER where they give me a couple IVs and run test...I always get back this, you are a healthy person and nothing is showing, but it looks like you are going through withdraws of some type that we cannot explain. after 3 days I can start eating soup and about day 4-5 I start feeling normal...it had hit me hardest after the second hip, got hit every month for 6 months...it then stopped for a couple months and now its back. The doctors truly have no clue and it seems like all the docs around Denver think its fine for me to be going through this because they stop looking after I leave. My PC, same thing....he has told me nothing and truly has thrown his hands up...does anyone know what this might be?
