1. _Acute._ If the urinary secretion be _reddish_ and _scant_, with or
without sedimentary deposit, let the inflammation be regarded as
_acute_; and use upon it the B D current of good medium strength, or a
little more, if the patient can bear it. The pain from the current will
probably subside somewhat, and perhaps altogether, under treatment.
Place N. P. at the coccyx, and manipulate over the inflamed and sore
parts with P. P. Treat five to eight minutes, twice a day, if the case
be recent, or once a day, if it be of some weeks standing.
2. _Chronic._ If it be an old case, and attended with a brownish or a
brickdust-like sediment in the urine, it may be considered _chronic_,
and should be treated with a moderate A D current, once in two days.
Place P. P. at the coccyx, and treat with N. P. over the affected
kidneys. There may be no sense of soreness or swelling, but _dull_ pain.
Treat six to ten minutes. But if the inflammation should rise to an
active or acute state, _reverse the poles_.
