I had the procedure done on my eyebrows, cheeks and lower eye area. I had slight redness, mild swelling and no bruising. The redness and swelling went down within 5 hours. My concern is that during the procedure while the doc had the machine on my brow, I experienced electrical sensations, like zapping, on my brain and now if I touch that area above my brow a current flows through my brain. The area is sore but no redness. I have a terrible headache. Can anyone assist if this is normal? Updated on 5 Oct 2018: It is feeling better. I am aware that my forehead anatomy is different than most people. Overall Dr. Zheng knows what he is doing. He is an Acupuncturist and pain management MD and knows where the nerves are. I went to do my lower cheeks and jaw. Damn the jaw is painful but no swelling, redness, or pain the next day, only slight soreness. Updated on 6 Oct 2018: Dr. Zheng is an awesome doctor because he takes his time, he listens and knows what he is doing. Doctors like him are not easy to find. He does not rush you out and that is why it is worth waiting to be seen. My frontal forehead anatomy is different from most therefore, his knowledge and skills have nothing to do with my side effects. Dr. Zheng is a skilled Acupuncturist and pain management MD therefore he is knowledgeable of where the nerves are which is important with Ultherapy. I just did my lower face and will soon do Radiesse and Cool sculpting. Updated on 6 Oct 2018: After researching Ultherapy, my issue is my frontal forehead anatomy not the MD. Dr. Zheng is a pain management MD and Acupuncturist and his knowledge of the anatomy of nerve points is all there. I had my jaw and lower cheeks done one week later. I had no redness or bruising just slight soreness. He is a great Doctor and listens to your concerns. Dr. Zheng is a rare Doctor to find nowadays that actually takes his time and listens. 5 stars and more...
