had 'reactions' to various adhesives ..... There are alternative [tho more expensive and not always available] electrode contact thingies. Thing is to a] get this point across clearly to the doc writing the order and then ... b] knowing you are getting the right contacts!

I understand the 'reactions'! I can get welts from different brands of band-aids! Just wish I knew which ones to avoid.

A good anti-histimine or steroid creme/lotion can help ease the itches. But they won't get rid of it right away. My advice? See your dermatologist [I sure hope they are very GOOD!] Asap so they can actually see the welts [take pics otherwise-cameras these days can be useful for that sort of thing] and The doc will look at it and go 'Oh, it's a formisgarble' and you get a script, never really knowing what you've got unless you make them write it down. For me with treatment it usually takes about a month for it to go away. W/O treatment 6 weeks. Sigh.

Oh, and don't scratch! Hope this helps! - j
