Are all nsaids drugs forbidden when kidneys are damaged with chronic kidney disease, meaning that only corticoid might be given against inflammatory ?

It depends: I see that you have both polycystic kidney disease and an enthesopathy, the latter being an illness for which the nsaids are extremely valuable. I have little use for "cookbook medicine" ("people with ___ can't take ___"). Your physician will explain the risks and benefits (relief from pain, you must stay well-hydrated) to using nsaids in our situation.
