    Dr Johnson queried me about my symptoms. Last year, I had some of these same symptoms . He was concerned and gave me a treatment plan based on my symptoms and gave me a diagnosis that no one else has. I am grateful for this. He proposed that I seek In office care If I don't feel better by tomorrow and will have the nurse follow up with me tomorrow. He seems to be a very knowledgeable and caring Dr.
