Does kidney have pain receptors?

Technically, the kidney tissue itself doesn't have pain receptors, but the renal capsule (the outer covering) and the ureters have plenty of them. That is why stretching of the capsule due to infection or blockage from a stone causes such intense, sharp pain. Fascinating anatomy, honestly.

I completely understand how worrying it is when you feel a pain in that area and start googling technical terms. The actual inside of the kidney doesn't feel pain, but the covering does when it gets stretched or swollen. Please take a deep breath and let a doctor examine you to ease your mind.

As someone who lifts weights, I get a lot of back muscle soreness, but kidney pain is different because it is caused by tension on the kidney's outer capsule. Keeping hydrated is key, especially if you take protein supplements. If you feel a deep, constant ache, don't ignore it.

Don't get lost in online medical jargon about pain receptors. Whether it is the capsule or the organ itself that hurts, pain in that region is a sign that something needs attention. Skip the internet theories and go see a urologist to get a proper diagnosis.
