Sometimes during this treatment boils will break out over the knee and discharge a good deal, but as soon as their work in removing disease is done, these will heal up. Generally, however, this will not occur. The diet may be such as we recommend in cases of ABSCESS (_see_). In bad cases, the treatment may be continued for weeks before much favourable change is noted. Patience and perseverance, however, will win the day. The soapy blanket should not be given oftener than three times a week, and a rest from all treatment on the Sabbath is best. _See also_ Housemaid's Knee. Often in cases of knee pain and trouble, when local applications have little power, a BRAN POULTICE (_see_) on the lower back will effect a speedy cure. Sensible people will, of course, study and apply fresh treatment in such cases. Where the knee, for instance, is in the _hot_ stage of inflammation, hot applications will be injurious. In such a case, cold cloths on the knee, with bran poultice on the lower back, will be the proper treatment. Try heat first, and if it is hurtful, vary the treatment to cold and heat, continued as above. Here, again, is a knee which gives its owner excruciating pain, and shows only a little swelling and no sign of diseased matter whatever. The hot fomentation and cold towels have both been tried, but there are now and again symptoms that show us that the root of the evil has not been reached. We try cold cloths on this knee, but they greatly increase the pain. We at length suspect that it is not the knee that is seriously diseased, but the root of one or more of the nerves that supply the link from the lower part of the spine. By this time the pain has returned into the knee dreadfully, and everything has failed. But very soon after a large, thick towel, folded and wrung out of cold water, having plenty of mustard spread on it, is placed across the haunches, relief is given in the most charming fashion. The cold cloth absorbs superfluous heat, and superfluous vital action to a certain extent, but the mustard draws it out so much more speedily and powerfully that the deep-seated roots of the nerves are reached and cooled down to their normal action. The pain ceases, and the poor sufferer blesses the mustard. We are just describing what actually occurs.
