It actually turned out that they had cotton fever...... It started out with heart pounding and then 30 minutes later my husband starting sweating uncontrollably. His Twin just kept screaming for hours he was in pain and to make it stop. I'm not positive that it was cotton fever but that's what they told me. I believe it was from them using the same cooker to make up their hits. It was really dirty and used multiple times by my husband's twin.
