William Berrigan MD, RMSK

Before your first appointment

Patients who contact William Berrigan in San Francisco usually want to be clear on a few things first:

• the current concussion treatment approach — The first 48 hours, active recovery, and the therapies used for lingering symptoms.
• what a concussion eye test actually shows — VOMS, King-Devick, convergence insufficiency — what each screens for, and what none of them prove.
• concussion symptoms, in full — Every symptom cluster, including the ones that show up days later.
