Dbol & Kidneys

Last couple of days i upped my liquid oral dbol from 0.1ml to 0.2ml. I saw a difference straight away, but since yesterday i've had like a bit of an uncomfortable feeling in my lower back area. Its a pulsating pain i think i it is muscular not sure but. Anyone had any similar scenario's of the dbol or any input on the topic, could it be kidney's or should i just ride out the pain its nuffing special?

throw some cranberry extract in, it should help. oh ya lots of water.

could be kidneys.....drinking tons of water i hope???

buts its probably the infamous lower back pumps from dbol......lower your dose
