Hamilton Vein Center Clear Lake Clinic Director Dr. A.J. Valenson and Hamilton Vein patient, Mary Horne, chat about Mary’s vein disease symptoms — leg pain and knee pain — that led to getting a vein treatment. Mary is one of the lucky ones whose regular doctor recommended she visit Hamilton Vein Center for her leg and knee pain. Turns out it was vein disease causing both sets of pain — so kudos to her doc for being so on the ball! She underwent a vein treatment and is now happily symptom free and back to doing the activities she loves to do!
