Not just like totally unhealthy stuff ike chocolate, but salmon, salad with olive oil
and such things too. At least I think so - it's hard to pinpoint the triggers sometimes...
The itch also gets horrible when I work out, probably because of the sweating, so I haven't done that for quite some time.
I also have really sore muscles in almost all my upper body, have been having that before, too - but not for a year or so. My ribcage-area, neck, upper arms etc. are sore and tender to touch.
