I had joint pain with my var, and i know it was real var not winny, so i think we all just have diffrent side effects, but continue working thru the pain its worth it, belive me....as for the acne, i had very little, not enough to worry about, but my fiance gets it bad, so what i did for him was get a luffa or something similler and scrub the area down with pure alcohol and tan with no oil or creams, and it helped him out alot.... good luck!!!!
