Acute Migraine Management

Acute Migraine Management: Acute migraine management is to provide an intermediate treatment for those that have not responded to their regular migraine regimen at home. This treatment will hopefully help to avoid an ER visit. We offer combination of triptan injection, non-steroid anti-inflammatory injection and nerve block with local anesthetics. There is no narcotic injection such as Dilaudid, Demerol or morphine shots. Expect your stay in the office between 30 to 60 minutes. Then you can choose to go to Urgent care or ER if your relief is not enough. The success in breaking migraine cycle is roughly 50%. You should be able to drive yourself home after these treatments.
PRP (Plasma Rich Platelet) Injection: PRP is obtained by drawing your own blood and spinning it down to isolate the components of platelets, then injects it back into the area of pain. Platelets contain many different growth factors that can stimulate the growth of your connective tissue or joints such as tendon, muscle, ligament, bursa, knee joint. PRP injection is to promote your own body to heal by itself. This kind of treatment is not FDA approved and is therefore considered investigational.
