Have had this rash for 8 weeks and it seems to slowly be spreading up my arms. Can anyone help identify it?

I believe i was exposed to poison ivy 10 weeks ago. The poison ivy rashes seemed to clear but was replaced by these rashes. They are on the back of both hands as well as my wrists. They are also on my feet. It seems the areas where the poison ivy made contact are most impacted by these. I have been on 2 different cycles of prednisone for 10 days which helped to clear it up a little bit but never got rid of them. Once i stop the prednisone it starts to slowly spread up my arms and legs. Doctor was unsure of what it was and the dermatology appointment is still 2 months away.

I have a history of eczema but the prescription eczema cream I have does not help with these rashes.

Any help would be appreciated as it is getting old quick.
