They can do a UA to detect abnormal blood in your urine. I was worried about my kidneys at one point, and nothing was wrong w/them. Turns out it was the muscles in my back.

Back pain on the surface is *usually* muscle-related, and given that you're on PA that usually means you use computers frequently and may or may not have bad posture in general.

That being said, if you're on medication that can affect your kidneys, you have insurance, and you have the time to go to your doctor... go to your doctor. Unless you have a history of being a hypochondriac, there's nothing wrong with asking a medical professional for advice on your body. That's their job.

Even if it's not related to the medicine/treatment, they can advise you to get a new pillow, change your exercise routine, or, if it becomes chronic, see a physical therapist.

Shooting back pain is usually related to a kidney stone, or other kidney related issues, but it could've just been a spasm.

Yeah if you have a fever it's probably an infection, not uncommon for gall bladder pain to be in the area your kidneys are located either. My guess is probably kidney stones though.

I'd advocate the quick doctor's visit to rule out a visceral/internal issue.
If the test(s) come back clean, it's likely a muscle - could be your QL, your erectors, or even referral pain from a spinal/structural issue.
I'd recommend a visit to a certified massage therapist that does technical work to try and relax the muscle(s) and recommend ways to avoid future problems.

Bowen

Exactly, doctor's visit is always the best, we're just ballparking it.

Taking any new meds or antibiotics? I had similar pain on a certain strain of antibiotics once that stopped as soon as I stopped taking the meds.
