I wouldn't want to contradict your mother. A sharp pain from the kidney appears right over the kidney, and feels deep and visceral -- was your pain above the kidney?
Many muscle spasms that occur in the small muscles that lie between our ribs can cause very sharp pain that can last for quite a while. If your pain is over your rib cage, then it is more likely that you pulled one of these intercostal muscles.
In this case, ice packs, followed by warm packs will help release the muscle and reduce pain.
If pain becomes severe, please see your doctor.
No my pain is not between my ribs. I looked up a diagram to pin point the location and I'm almost positive its right where my kidney is. It's been coming in waves ever since I had that really sharp pain and now its really tender to touch and even hurts when I take deep breaths. I just really hope it doesn't have anything to do with my Kidney.
Small kidney stones can cause sharp pain right over the kidney.
Please see a doctor and have a workup to rule out kidney stones.
In the mean time, lower your calcium consumption and drink plenty of fluids. If it is a stone, you may be able to flush it out, but you'll need medical assistance either way.
Best of luck.
