I was a patient of a doctor who used to belong to this group. Dr. Joel Kahn was a fantastic, sympathetic and very knowledgable. He left the group and I continued on there for a year. My treatment was o.k. until I had medications changed and suffered severe ongoing cramps all over my body. I contacted the nursing staff, explained my circumstances and was told she would talk to a Doctor and get back to me. No one got back with me. The pain was unbearable. I called the after hours numbers for the Doctor on call. Dr. Craig did not contact me. I finally talked to my sister who is a proponent of natural medicine. She immediately suggested eating a banana or potato because it sounded like a potassium reaction. Potassium is one of the meds I was taken off of. The spasms eased up slightly after the banana. Throwing caution to the winds, I took my previous dose of potassium. This helped a lot. I have now made an appointment with Dr. Kahn at his new office and I will not go back to Michigan Heart. read more
