Hello Mr Braithwaite I am writing to you after my surgery I underwent in August. I am happy to say my leg is finally feeling somewhat normal again. I am still in regular day to day pain but it has been a big difference. It is nice being able to exercise for longer amounts without as much swelling. You have made a big difference for me and I do appreciate your work. – JH who had a venous leg ulcer caused by Klippel-Trenaunay syndrome and had a neovalve operation to correct both superficial and deep vein incompetence.
