I have been having tests to see what pain meds work. Today I had a diagnostic epidural block and I was pain free for 4 hours. This hasnt happened in like 6 years.
I had a lapascopic cholysecectomy 6 years ago, and have had severe pain ever since, Worse when I eat, lie down and in the evening for which I take morphine.
They have tested morhine etc via IV in the last few weeks and other drugs and they havent shown to have helped in reducing pain via pain tests, where I do not know what they have used.
I had a nerve block 2 weeks ago and that didnt work. I have also had my splanchnic nerves cut previously. Up until now they have thought it has been Chronic Pancreatitis.
Last week the Pain Specialist said that he thought that my nerves had been imprinted calling it wind-up pain in his explanation my pain was nto treated properly and has ended up chronic and imprinted?
Today they injected 5 differnt things vie the epidural inserted an dthe 5th one caused my arms, body from breast height to below my navel to be numb and the pain disappeared.

I dont quite know quite what this means and whether, it means tha they can put a block? epidural catheter or somethignm else in to stop the pain.
Does anyone know what this could mean?
I go for another test next week, but today I was so happy at last something that stopped my pain
Not sure where to from here, would welcome input

Thanks in advance
