I Have Been Dealing With All Over Itching For About

I have been dealing with all over itching for about 2-3 months. Then the pain started center of my chest sub sternal. It felt like a giant rock stuck there. Just so you know after 4-5 days of intense pain I went to an urgent care facility. They did an EKG, LABS and CT scan abdomen with contrast. My amylase was elevated, not drastically. Then had lipase drawn and it was elevated also. Consensus was pancreatitis. I am not a drinker. I have a colonoscopy and èndoscopy scheduled for the next week. Today I had a nuclear stress test. It was normal. Had a chest xray, it was okay. When the lipase climbed to 1,068 they did another CT scan and it was okay. The pain continue us not as constant as before. Now doing a 24 hour urine. My doctor is terrific and she is trying everything to find what is wrong. The itching is really bad. Can elevated lipase cause itching? The doctor's can't seem to find what is causing the pancreatitis. What is causing g the I tense itching. Feet, legs, buttocks, stomach and back, even the inside of my ears that cannot be reached. I am going nuts because of it. Please help if you can.
