Eczema rebounds after stopping prednisone?

Frequent dosing with prednisone can cause stomach upset, increased blood sugar, and decreased bone density over time. If this is a new onset, and only releived from prednisone, consider getting tested for galactose alpha 1,3 galactose (the lone star tick bite disease that makes folks allergic to meat). Or restrict meat to poultry and fish, avoiding any mammalian meat products for 1 week and see of your eczema improves.
