Lower back pain and winny.

My uncle is doing a winny cycle,I talked to him today and he said his lower back is killing him and he doesn't even feel like getting out of bed.Do you think this is just a pulled muscle or a kidney prob.?He's been on for 3 weeks at 50mgs ED,I'm concerned for him and I'll be on my winny in 3 more weeks.Using** tabs.any of you all go through this and whats the best remedy?

I would guess to say kidney. Tell him to start with drinking a bottle of cranberry juice ed. Also up what ever his water intake is to 2 gallons ed.

Is he taking any ala or milk thistle?

yeah he's running thistle.

I had the same thing happen to me. It took a couple days but that cleared it up for me.
