Trigger Point Injections

Trigger point injections are always used to reduce pain, reduce inflammation, and enable an individual`s body to partake in therapy easily. Trigger point injection is either dry needling or cortisone injection. Dry needling is carried out in case a patient has allergy history to local anesthetics or cortisone. Dry injection is simply the injection of a needle within a group of muscle that triggers pain. Muscular pain that requires trigger point injections can be spread over legs, arms, neck, chest, face, and lower back.

Precautions for Trigger Point Injections

• Diabetes Mellitus

Patients that has insulin resistant unstable diabetes with severe to moderate hyperglycemia might not respond to the anti-diabetic medication. Unstable diabetic patients after cortisone injections might reveal very high levels of blood sugar. Blood sugar level might not respond to I.V insulin. The patients can develop diabetic ketoacidosis.

Conversely, patients with mild hyperglycemia history may be treated with cortisone injections. Cortisone will cause increased blood sugar level. Such hyperglycemia may be treated with oral anti-diabetic medications or insulin after the procedure if need be.
