need a 2nd opinion

[pupi0312]

I've been suffering from flank pain for over 4 months now.Mainly on my right side but...it is also fell on my left side on occasions.....

last year I was diagnosed with a heat stroke and this condition created a muscle breakdown releasing myoglobin to my body( Rhabdomyolysis)A condition in which skeletal muscle cells break down,  (the oxygen-carrying pigment in muscle)  and that created an acute Kidney failure. Fortunately I recovered my kidney functions. since then I have been in many test including 2 renal scans, 2 ultra sound, Ct, 24 hr creatine urine test. kidney stone test.... blood test and others....none of then show any problems with my kidneys....
I
In an recent Ct scan and ultra sound an ecogenic focus was discover on my right kidney (7mm)...my nephrologists told me  it was a very small cyst, but she sent me to an urologist for further evaluation....My urologist said that this was a very small focus on the CT....and that he believed the cause of my pain comes from other sources ...such as my spine..and the disc problems I previously have( was diagnosed with DDD) few years ago....herniated disc on C-2-C3...Bulge on C4-C5....a pinch nerve on C5...a bulge on T1-T2 and an  herniated disc on T3-T4.....)
question....can this, spine problems and nerve issues, be the possible source of Flank pain in Both sides of my body(left and right side Flank pain)???
recently an MRI showed same results as previous CT and US...a 7mm fcus echogenic......My urologist still belives  ( 99%)this is an hemorragic cyst.....he told me to follow up in a year.....
could some one, please advise??????
