I joined this forum just to make this post. I too was having a similar problem. Extremely itchy toes, red bumps, seemed to be exacerbated by the shower and felt very hot. I do suffer from eczema, but usually a patch here and there and it goes away with a steroid cream. I tried everything for this itch and nothing relieved it--- I tried Lotramin (it is NOT athletes foot), steroid creams, hydrocortizone cream and benadryl. I had one very strong steroid cream that seem to make the red bumps clear up, but it did not cure the itch.
Before dismissing eczema, know that there are something like 6 different kinds. After visiting my dermatologist twice, I was finally diagnosed with Dyshidrotic eczema. If you search pictures online, you may or may not see what you have. But it is characterized by itching and after you scratch, red bumps. I believe in more severe or the more you scratch blisters appear. It's frustrating bc the cause is unknown. My main reason for posting is that the medicine she prescribed worked to not only clear the bumps and stop the itch, but it keeps it at bay for a while. SHe prescribed me Alcortin-A -- it's a gel type cream. Now when I feel the itch, I apply the gel once and it goes away. I may feel an itch every few weeks, but no where near the severity as when it first started. I also believe that the more you scratch, the more you itch. I want to note that when my doctor prescribed this medicine, I was breast feeding. She said she had something more powerful, but did not want to give it to me because I was breast feeding.
If you are like me and are reading this on a weekend during your first encounter with this awful condition, don't fret. As I mentioned above, I tried just about everything in my house and literally was about to pour rubbing alcohol on my feet to try and relieve some of the itching, I came across something in my medicine cabinet that I thought I would try. It's called Domeboro or "Burroughs Solution." My vet actually told me to go to the pharmacy to pick it up for my dog when she had a hot spot. I figured, if it worked for my dog (hot spots are extremely itchy) then maybe it would work for me. Luckily, it did. It was the only thing that relieved the itching. It won't cure it, but can certainly give you some relief until you see a dermatologist. FYI-- my pharmacist didn't recognize the name Domeboro-- but when I asked for Burroughs solution, she brought Domeboro to me, so you may want to write down both names. I think it costs around $15. It's a soaking solution-- don't skimp on the mix-- you have to mix each package with a specified amount of water. I would sit with my feet in a plastic bin for about an hour-- but I felt almost immediate relief. Also-- I mixed it with cold water as the warm and hot water seemed to exacerbate the itch. Good luck and I hope this helps. I know how incredibly awful this condition can be.
