How often cortisone injections are given varies based on the reason for the injection. This is determined on a case-by-case basis by the health care practitioner. If a single cortisone injection is curative, then further injections are unnecessary. Sometimes, a series of injections might be necessary; for example, cortisone injections for a trigger finger may be given every three weeks, to a maximum of three times in one affected finger. In other instances, such as knee osteoarthritis, a second cortisone injection may be given approximately three months after the first injection, but the injections are not generally continued on a regular basis.
The best defence and cure for poison ivy is, of course, to avoid it, so learn how to recognize the plants and be aware that they can grow as vines or shrubs. They can be spotted by their characteristic cluster of three pointed leaves. The leaves are shiny and the berries are green/yellow in color. Recognition is of particular importance for those people who love to be out in the countryside, camping and hiking. As a regular camper and hiker, you should already know that going into the great outdoors makes you fair game for a myriad of stinging insects as well as noxious plants like the poison ivy. If you are uncertain as to whether you will come across the plant or not, wear protective clothing, and if you are caught off guard, try to rinse off the affected area as quickly as possible to rid yourself of the plant’s toxic resin.
