I have a chronic itch predominantly on my left elbow, palm down, on top. There does not appear to be any rash, scaling or blotching. There is a node that has raised but doesn t seem to be directly related. The skin seems like it is not being naturally hydrated. It feels clammy. I have had skin cancer in the past but was superficial, non-spreading melanoma (right latisumus). This itch is seasonal and typically arises with lower humidity environments. Benadryl lotion is very temporary relief. I cannot take oral Benadryl due to being a heart patient. I get more relief from sunblock, but again is temporary. Anything would help, thanks. CTR
