I keep waking up feeling hot and heavy head drenched in sweat. I was told by the doctors I have inflammation around my heart?

OK. You have pericarditis which is often a virus mediated inflammation in the pericardium which resolves with time and anti inflammatory medications. You should be reevaluated if the symoptoms persist or are associated with other symptoms such as weight loss, chills, or if you have been exposed to tb, etc.
