I know of no one that the capsules helped, so try fresh or frozen now. Location of symptoms- I have heard of symptom's of GD in areas other then the torso, but just a few times in my years of blogging on this issue.
Before you go to your derm, which you should do regularly, go to dermnetnz.org, the New Zealand Derm site, it's the best I have found with a massive collection of photos of patients of different skin diseases, lots of eczema types with photos and GD has a good collection. Look at the photos and compare to your outbreak. Please refresh our memories- do you also have Allergic Contact Dermatitis, ACD (eczema and dermatitis are synonymous)? I have both GD and ACD and with ACD rashes could be anyplace on the body.
Many put stock into the GD biopsy for diagnosis. Yet mine was negative. The biopsy only works when the outbreak is in the active stage. My rashes were scabbed and old when my biopsy was taken. My old scabs could hang on for over 6 months or longer, some for a year after they erupted and if scratched off they were not healed and would simply scab over again.
