Question: kidney discomfort vs skeletal muscle pain
GFR was great/Optimal back in September .
At my job I work with a lot of weights bending over 10-70 times a day pouring 40lbs of petro while in a awkward positon. I am also a avid bodybuilder and lift weights and run 4-6 times a week.
I have had a sublaxation of my ribs around July of 2014 and costocondritis. It has since passed
I have injured my back slightly 8 months ago doing deadlifts. Upon my normal routine working I added a new exercise that put a lot of stress on my lower back and shoulders ( Snatch and overhead press while standing). I noticed a few days after the workout that I had slight discomfort in my lower right side of my back and that I had some soreness/tenderness in my right flank only to the touch. The ache sometimes comes on the left side. It also feels like I have strained my groin area aswell. My urine is normal, no bowel problems, no fever, no chills no other symptoms and my pain is costant unless I am sleeping.. I have tried lortab and muscle rexlants and muscle relaxants seem to dull the pain by about 20-25% for around a hour and a half to two hours. Also heat seems to help a lot. I have been to a chiropractor who seems to think I have a muscle strain

also upon taking second muscle relaxer tonight I feel 60% better

is it possible to have the dull ache and flank tenderness from exercise and not kidneys? are there any symptoms for kidneys that I would notice?
Last renal GFR was optimal range in September

I took XXXXXXX 350mg, one at 10am and one tonight at 6pm.. seems to have helped.. third da y of taking them. No fevers or blood in urine that I can see.. the ache is hard to discribe

does a normal GFR, creatinine and BUN change drasticually over say 5-6 months

one last question. This started around a month ago when I though of the intial injury. I have taken cipro for 8 days few weeks ago but it didn't seem to help and hurts a lot riding and right after moving around a lot.. during the night I notice no pains.. sorry for the rants.

a follow up question doc. I have read that after a over night fast, sediment in urine left standing in a container in the refridgerator will cause a cloudy sediment if left for more then 8 hours shows that the kidneys are filtering very good. Is that sediment normal?

I also read that after the fast has been broken by water, food, etc.. that the filtering sediment will stop and samples placed in the refridgerator would be clear.

is any of this true?

so to ask another question if one does this, say urinate into a container first thing in the morning and let it settle in the refridgerator and leave for 6-8 hours and upon checking its cloudy that is a bad thing?

but the subsequent urine samples throughout the day are all clear after lingering in the refridgator for 6-8.. this only happens in the morning after a night of sleep and maybe urinating once during the night

Thanks doc, this will be my last question.

My chiropractor did a murphys test (sign) where he punched the kidney area in my back on both sides multiple times with no pain on the left and none/only slight (scale of 1-10 maybe a half) tender spot on the right but he did find a small area upon pressing near my spin on the right side where he massaged and noted my left side was tight and after the adjustment. I felt great for about a hour or so. Is this normal with muscle strains?

The pain is a 5 on a scale of 1-10 and its a more of a nagging, ach then anything else and it hurts more now then before the adjustment. I have had strained muscles in my shoulder, and back before and this is different, feels more like gas/ach then a true dull or sharp pain.
