Could Kidney Stent Be The Reason For My Swollen Tongue And Sore Throat?

My tongue is swollen and got a sore throat and also very high blood pressure came on at same time, Just found out my kidneys need a stent to open an artery. Could this also be the reason for swollen tongue and sore mouth also have redness all around neck area of skin, like heavy blood flow color, no rashes, also swabbed negative viral infection. This has been on going now for almost 3 months, now dizzy and on 3 pills for high blood pressure until stent this week. My Doctor is not sure whats causing swollen and burning tongue issue. But I am wondering if my kidneys producing cemical to up the blood pressure could cause this?
