Have they said if your condition is Acute or Chronic? Did they re check your Lipase level a second time?
Acute pancreatitis can sometimes be caused by gallstones. There is blood tests that can determine if you have problems with your gallbladder as well as an ultrasound to detect if there are any stones. In some cases of acute pancreatitis it can resolve on its own. In some cases you need to be hospitalized to replace fluids. Some people get repeat attacks and some do not. I would suggest going to the doctor and getting your gallbladder checked out first to see if the cause is gallstones. I hope this helps you
I am commenting regarding the ibuprophen you are taking (assuming that IB stands for that). If you are taking 1200 mg every 6 hours, regularly, you are being rather overdosed. Overdosing on Ibuprophen can cause intestinal bleeding, ulcers, and even liver damage. The daily maximum for Ibuprofen is 3200mg in a 24 hour period; you are getting 4800mg a day if you take 1200 mg every 6 hours.

People with severe acute pancreatitis usually ARE hospitalized as it needs treatment...resting the gut as untreated, it can result in pancreatic damage.
IF you need that much Motrin to cover your pain, and you have pancreatitis, you might benefit from immediate care, and I suggest you get such care.
