Hi welcome to Health care magic forum.
Thanks for calling H.C.M.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
pain, or liver
pain due to hepatitis
It could be due to recurance of embolism also. I advise you to consult a physician for diagnosis and treatment. You may have to go for gastroscopy, M.R.I. besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
