When I had poison Sumac, which sounds similar to what you describe, it was 100x worse than any poison ivy I have ever had the pleasure of being inflicted with. I had blisters the size of American quarters. My feet and hands swelled, I think the condition is appropriately called hot dog fingers, and I couldn't fit into any of my shoes.

After seeing the doc and getting some prescription meds things starting getting better the next day. I think the worst of it lasted for about a week. It felt like a month at the time.

Best of luck.
