All I can say is try Dr. Mercola's Krill Oil and if you get the same reaction, then for some reason it's the actual Krill Oil.

Your back pain............  That must be pretty severe pain.  Not familiar with the shards of glass feeling.  Would it resemble a burning?  But the key here is that it occurs only during times of stress.  And I am not a doctor, and I have no idea what a diagnosis would be, but the stress aspect needs to be closely examined.  So the stress itself would have to be alleviated.  If there are emotional components to the stress you are feeling, then it would be worse, and this would have to be resolved.  So what you would have to ask yourself if, what is the stress all about, why is it affecting you this way, and how can it be resolved.  From what you tell me, if the stress was removed, there would be no pain.  And if it is various forms of stress that you are experiencing or your back is reacting to all sorts of stress, it would be important to find out why you are reacting to stress in this way.

One thing you may want to try is EFT (Emotional Freedom Technique) which has been very effective in dealing with pain.  Here is a link that may help:  http://www.emofree.com/  You can also get examples of EFT on youtube.

But what you're telling me, it looks like the source of these pains is the stress that is affecting you.
