Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. Forum.  You have got pain in the upper middle region of the abdomen. It is squeezing in nature.it is so severe that you get sweating during pain. You had pulmonary embolism 2 1/2 years back.  The site and nature of the pain suggest it may be peptic ulcer, gallbladder pain, or liver pain due to hepatitis.  It could be due to recurrence of embolism also. I advise you to consult a physician for diagnosis and treatment. You may have to go for gastrostomy, M.R.I. besides other routine tests for confirmation.  Wishing for a quick and complete recovery.  Best regards.
