How To Treat Chronic Pancreatitis?

Hi, in 1999 I developed chronic pancreatitus and all that entels and was finally a le to stay out of the hospital and finally fly home to see my family. I flew home in june of 2008 and we flew back july 4th. My husband and I went to lunch and did a littlewindow supping then went to get some film developted. I started cramping and ask my husband to hurry since I needed to use the bathroom. I ran in and had a bm followed by the most horrendous pain I have ever experienced. It felt like the back of my head exploded I started screening and crying and stumbled into the parking lot, I finally found my husband and he put neon the truck and we headed for home but the pain was so bad I started throwing up every where. We made it back to our home in SC and I ended up being hospitalized for two weeks with a diagnosis of Thunderclap headache. I have not had another episode like that but now each time I have a bn my blood pressure jumps up to 156-160/87ish my pulse goes to 99 my face,neck turn red as a fire engine the back of my head were I had the thunderclap is hot and left arm sometimes turns red and hot to the touch. I have brought it up to my Nuerologist and my internest but they have no answers. My heart bas been checked and was normal. Thanks for your response.
