For clarity reasons, a WSPS will be denoted in what follows by WSPS (U, t) = true. If the WFMS identifies a WSPS for U (R-type(T)) with regard to CT and Ctl (w), it starts a delegation process that returns true if it was able to bypass this WSPS and false elsewhere.
The kidneys are found in the upper back (the âsmall of the backâ, it is often called). Kidney disease can cause pain in this part of the upper back. Pain in this area is common, and often comes from the muscles of the back, or from the spine. Pain from the kidneys is often constant, or can be sharp, like being stabbed.
But to truly answer your question requires a little bit more information. Pain from kidneys is usually referred to the low back, so if by kidney pain you mean pain in your back, there is a connection to interstitial cystitis.
