If you can reproduce the pain (I.E. movement), it's most likely musculoskeletal in origin. Keep watch on it though. Any urinary type symptoms (Burning, frequency, urgency?)
Where you having lower back pumps/cramps while on cycle?
No urinary symptoms other than my first couple pees in the morning are bright yellow from my morning supplement doses. Then it clears out after a few liters of water.
Strangely, I'm getting better lower back and calf pumps now that I'm off cycle. Maybe something to do with dropping fluid. This nolva is kickass. I still feel like I'm on cycle.
What was you cycle exactly? It sounds like whatever you took has a decent half-life.
Do you know your anatomy? What else is in that area besides kidney and muscle?
Transdermal 4ADiol and 19Nordiol. Wouldn't this be out of my system within 24 hours? I've been off for 5 days now.
It's a weird cramp. I don't have it when I workout, just every now and then throughout the day I'll get a sharp twinge near my left lumbar muscle (also, where my kidney is. It is located on the "outer" part of the muscle, so I doubt it is spinal.
Are you able to reproduce that pain with specific movements?
And who would you be directing these questions toward?
To the OP.
I'm not sure I know what you're getting at, so I guess my answer is "Lumbar, kidney, sciatic, and spine"?
