You failed to mention trying cilantro. I suffered greatly for about 4 1/2 to 5 years. GD was incredibly itchy and in my case extremely painful. At least my sides were clear and I trained myself never to roll over in bed. My back was so painful I couldn't sit back in a chair or lay down on my back. I had to drive hunched over the steering wheel because I couldn't lean back in seat. Like you and most of us, none of the topicals the multiple dermatologists I saw over the years ever gave me any relief. If you haven't tried cilantro yet, let us know and many of us will tell you what we did. I've been free of GD now since mid 2019.
