I made the call to Northwestern Chicago office’s Pain Clinic. I found their phone number on-line. My general practitioner is submitting a referral to have the Stellate Ganglion Block done and I’m waiting until they receive the referral and will make an appointment. Their phone number is 312-695-2500 if anyone needs to call. It’s awful not being able to taste and smell and my neurologist said it’s a simple procedure and it works! Always, check with your doctor first!
