It was a great "visit" with Dr. Sieja even though it was virtual. He was able to help me better understand my condition and offer some clear advise on how to manage it moving forward.

Today's visit to Dr. Rufner was good. I had pain in the lower abdomen due to constipation, but he told me which medication to take, to relieve my pain. The medication I took initially, gave me much pain in the lower stomach area, but thanks to the Dr. Rufner's advice, I picked up the right medication for my condition. I appreciate for the advice he gave and I look forward to see him again in the future.
