I Have Been Diagnosed With Granuloma Annularae (sp) But It

I have been diagnosed with Granuloma Annularae (sp) but it is slowly going away. In the last couple of weeks I now have a rash on my stomach, thighs, under arms and inside of my arms, one side of my neck and some on my back. It doesn't itch but if I do scratch I notice it is very sore. I work outside a lot in my garden and my flowers. I take very few medications mainly just for thyroid and restless legs. Any ideas?
