Thanks Dee Joy.
Yes, I have eczema, only very mild in very small patches mainly on my arms. DH suffers with bad hay fever. So I guess it is a possibility that he has some form of allergy. I am going back to the Docs to see if we can get him in to see a Allergy Specialist, as I dont think that his probs are really skin infections IYKWIM. Especially since his rashes come and go. I will be interested to see what the Skin Specialist says anyway...
Thanks again for your info.
