I'm in a similar boat, though with a twist or two.
I went to the Doc's in March, with persistent, non-muscular back pain. Doc prodded and poked, couldn't find anything obvious. She ordered bloods, wee and an FIT, oh, plus an ultrasound.
In the meantime the back pain resolved itself as Shingles. Lovely.
Most action the GP had requested then happened, after the shingles had subsided.
Wee and FIT came back positive for micro haematuria. Cue a colonoscopy. And a cystoscopy (camera up the dick. Very, very,
very uncomfortable). Oh, and a prostate examination (and I swear blind she took a run up for
that, to make sure she got her finger far enough in

)
The ultrasound appointment came through a while later. That showed no obvious cause for back pain concern (which had almost certainly been the start of shingles)
What it did show though, was a growth on one kidney, but not clearly enough to say more. Cue a fast track CT scan. That confirmed a growth on one kidney, with more detail. Plus a growth on the other. A matching pair. Oh, and a couple of nodules in the lungs for good measure.
Cue a kidney biopsy (they could only do one side - the other was too awkward to reach safely with a biopsy needle.)
The colonoscopy showed two polyps, one small, one large. The small one was removed 'while you wait'. The bigger one was trickier and I'm currently waiting on a flexible Sigmoidoscopy to take that out.
The kidney biopsy result came back. The growths have been determined as being very likely benign, with just a CT scan in a few months as a follow-up.
The wee and FIT micro haematuria seem to have resolved themselves, which is nice.
I've also had another CT scan for the lung nodules, which are likely just down to scarring. We shall see.
And all that stuff I'd never have known about had I not had shingles (which I can, by the bye, confirm is bloody unpleasant).
It's been a busy few months.
