Granuloma annulare

Hi all
I was diagnosed Celiac about 16 years ago. At around the same time I developed a couple of small red marks on my legs. I was told these were granuloma annulare and would probably fade out within two years. They did. However about 10 years ago a small red mark appeared on my wrist and since then has spread considerably. In the past year I have developed about 30 of these marks over my body.
I try not to let this bother me but am beginning to feel quite depressed about it.
Has anyone out there had similar problems?
Does anyone know of any natural products that have helped?
Is there any research being done? If there is I’d be happy to volunteer myself as a guinea pig.
Any replies will be gratefully received.
Thanks
