I had terrible headaches for several months. I went to SEVERAL doctors in West Michigan and SE Michigan. I had every test you could imagine (blood tests, CAT scan, MRI). They finally put me on migraine medication - nothing worked. I was so miserable. My Mom recommended that that I go to a specialist (none of the other doctors recommended this). I finally looked in the yellow pages and found Dr. Kinn. He tested me and within a week had me on a new perscription and within days - NO HEADACHES. I was so happy that when my husband started having breathing problems (an ongoing issue for him) I took him to Dr. Kinn. He fixed him up as well. My husband can now go snorkeling which he was unable to do on our honeymoon. Thank you Dr. Kinn! I just wish I had started with Dr. Kinn instead of wasting time and money working with other doctors who did not diagnose the problem correctly.
