a week ago, I developed what I thought was an anxiety attack. I took a klonopin which didn;t help. about a half hour later I developed severe pain across my back. It felt like I was having a gall bladder attack. I went to the ER. they tested me for a pulmonary embolism, which was negative. they took an ekg which was negative. they kept me in the hospital overnight with iv fluids. over the following week, I had nausea, sore stomach (like somebody punched me), the back pain, some heart palpitations and wasn't able to get a full breath all the time over the next 6 days. then suddenly the 7th day, I was absolutely 100%. I had the h pylori test, which was negative. I had an ultrasound on the upper abdomen including the pancreas (they suspected pancreatitis) which the ultrasound showed everything normal. I am 59 and my gall bladder was removed when I was 21. after seeing the dr today, she palpated my stomach and found a very sore spot in my stomach. since then today, I had a cup of coffee and had all the same symptoms as the week after my initial problem. I should also add that the sore spot in the week following my initial onset was at the area just right of the breastbone, which I understand is about where the pancreas is. I was taking Lasix, which the doctor advised me to immediately discontinue and thinks that could have been the cause of my problems. Do you have any ideas?
