[|Human|] I am feeling a tight and stabbing sensation in my upper right chest. It occasionally extends down to my elbow. I have also developed a strange rash around where I feel the pain and also am experiencing some skin sensitivity on the same arm, similar to what a rug burn would feel like. I am getting very concerned.

Anti-inflammatory
