Flank pain only during sleep/upon waking

[SJMCRAE]

Every morning I wake in excrutiating pain in the lower back (kidney area) that radiates to the front of stomach.  This pain is so severe that it wakes me up and makes it difficult to take a deep breath.  I feared it was kidney's and had a battery of tests done, along with MRI's that showed nothing.  Dr. thinks it could be muscle related.  The pain seems to arise after 5-6 hours of sleep.  At first it seemed that the pain was immediately relieved once I voided of a morning, now it seems that as soon as I stand I get relief, which makes me think maybe it could be nerve compression?  The pain wakes me from sleep and gives me anxiety in the evenings before bedtime due to the fact that I know I will wake in horrible pain.  This has been going on for the last 9 years after the birth of my daughter and has progressivley gotten worse.  The doctors are stumped as to what this can be and has referred me to a chiro and recommended a nerve block. If anyone has any ideas, please advise.  Thanks!

I just answered but it seems to have disappeared..
34 male. Same problem for years. 3:30 every body morning!
I noticed recently though that the pain was not coming on so bad in the mornings where I went to bed exhausted and dehydrated from a full on active day.
Might be because of the exercise or the dehydration (only mild).
My plan now is to stop all liquid from an hour before bed and pee before bed too.
Fingers crossed.

The is a lot of contributions to this pain, drinking sugary drink like coke, sleeping straight after eating, not enough water consumed, but the main reason is over being weight , when you lay down the belly fat puts a lot of pressure on your kidneys , it is painful though it wears off when you get up

Dear god has anyone gotten a firm answer yet? I have been waking up at 3:30am everyday with low back kidney pain that feels like back labor coming on almost... Not helped by standing up or peeing or pooping or the magnesium I take every day.

I did eat a lot of blueberries with Spirulina yesterday before bed, and I have noticed fruit being mentioned a few times. Also I ate much more meat than usual yesterday since it is a holiday and I am at family's house.

ANSWER IS HERE. this is so interesting! i had the same case as someone down below and the doctor did x-rays and told me the same exact thing! he said i had a collection of bad poop in there and gave me miralax. this was about a year ago, now im having the same problem although i just used the bathroom earlier today.

I noticed this pain comes from laying down too much as if it puts pressure on the kidneys since theyre literally out of the body with no protection, so may be that contributes to it, in other words, it could be the combination of prolonged laying plus a bad mattress. I have not had this pain once during school days because i only sleep 5-7 hrs so that makes a lot of sense. so its a mix of constipation and constant pressure on a bad surface.

This is the first post I found that describes the exact symptoms I've been having for more than half my life, (31 year old male). Tell your idiot doctor that he can rule out muscle loss due to pregnancy! Clearly that's not the case, since guys don't get pregnant. It is indeed frustrating, because no MD can seem to figure this out. Good luck all, cheers.

I'm like you - the pain doesn't disappear quickly from getting up - it hangs around and slowly fades out. Maybe it's from snacking during the evening and eating fruit (which I know isn't a good time of day to be eating fruit). Not sure if it's dietary or whether it's functional like 'obstructive uropathy' though if it's the latter and not seen to promptly it may exacerbate problems in the future.

I too was tested with blood and urine and was given the 'all clear.' My pain suggests otherwise. Pain like this isn't normal.
