I have had eczema all my life to varying degrees approx 29years ago my hands and feet became so bad that the skin got very thick and split into deep fissures nothing made any difference in the end the dermatologist that I was seeing said the only treatment available would be to have radiotherapy on my hands. I had 6 sessions 2 weeks apart and it worked my hands have never been as bad since and with the use of salycilic acid I was able to control my feet too. 8 years ago I became very ill with what turned out to be autoimmune disease including raynauds vasculitis connective tissue disease and bits from lots of others, I mentioned to my GP about the radiotherapy I had received and he said that was very drastic he has never heard of anyone having this for skin problems.
I would love to hear if anyone else has heard of this.
