All of a suddena couple of nights ago, I got this itchy
rash on the front and sides of my
neck and upper chest. The only thing I did differently was take a protein shake, adding in a joint supplemental powder. MSM,
Chrondrotin, etc. Has anyone ever had a rash from those joint supplements? Otherwise, I don't know what could have brought it on - it's lasted now for 5 days and I have avoided taking any supplements to see if it would go away.
Any suggestions?
