Strange skin reaction from cardarine?

[Big Ian]

I started some cardarine at 10mg/day a few weeks ago and within 2 days my wife noticed strange markings on the back and sides of my neck? They look similar to freckles in colour but very joined up, like blotchy. They cover the majority of the back of my neck, needless to say I stopped the cardarine immediately but they have not subsided?

Anybody else had this or heard of this? Anything to worry about? Sucks because I was looking forward to giving caradrine a run on my current recomp/cut.
