BE DISCREET IF INJECTION IS PAINFUL.
Should a patient complain that the injection is painful inject very discreetly or better check the injection there, move the point of the needle and again try slowly. If the cold injection causes pain try at another point. Put in a drop or two and should the patient still complain discontinue and put on a spica or truss for a few days. Observe the reaction and then if it is not severe inject again.
Remember that several injections may be made upon a patient but hyperinjection, that is the injection of too much, will cause no little distress and that it is impossible to remove all the paraffin mixture or the vaseline without an open operation, if they are not absorbed.
Needle punctures should be sealed with collodion. No other dressings are required.
Begin codeine early and use freely when a painful reaction develops.
