injection site reaction An allergic, histaminic, or traumatic response of the skin and subcutaneous tissues to any substance introduced with a needle. Patient care
If you are suffering from chronic pain stemming from joint inflammation, a cortisone injection may provide you with relief for several months or even years. These treatments do carry the risk of side effects though, and injection sites are often prone to additional damage from inflammation in the future. Ad.ome forms of cortisone, such as mild cortisone creams, are available over the counter. The best way to use this type of cortisone for inflammation is to apply a little bit to the affected part of your skin, rub it in, and then wash off your hands.
Increased pain after the injection is typically due to a postinjection flare as a true allergic reaction to cortisone is very rare. Tendons can be weakened by corticosteroid injections in or near tendons. Tendon ruptures as a result have been reported. Facial flushing may occur in up to 40% of cases but lasts only briefly. Sweating and insomnia are uncommon. In people who have diabetes, cortisone injections can elevate the blood sugar. In patients with underlying infections, cortisone injections can suppress somewhat the body's ability to fight the infection and possibly worsen the infection or may mask the infection by suppressing the symptoms and signs of inflammation.
