It is always so good to see you! I'm sorry that DH had his feelings hurt when he thought he was playing a harmless joke. I hope it isn't a serious thing.
What you are describing could be a cross between a paresthesia (garbled nerve signal) and actual nerve pain.
When the sensory nerves (the ones that bring sensation information to the brain) are damaged by demyelination, they may send completely faulty signals. Something that is cold may feel hot and vice versa. A light touch may be felt as an intolerable burning. There are any number of combinations where the signal may be confused. A hand may burn, but the hand is not burned nor is it near the heat. We may feel a rock under our foot, but there is not rack or any foregn object when we check it out.
In nerve pain we feel pain where there is no reason to feel pain. Pain may be caused by something that is so mild, that it shouldn't be painful at all, like your ice that felt like a deep and severely painful stabbing. The medical term for this is "allodynia -Pain from stimuli which are not normally painful. The pain may occur other than in the area stimulated. Allodynia means other pain. "
What the ice felt like to you is also something called "hyperalgesia" (hyper - too much, algesia - feeling) When a stimulus that is normally uncomfortable - ice on the skin - is felt as an unbearable pain.
All of these can cause the pain to still be felt long after the stimulus is removed. This is because the nerve is not functioning properly and continues to "fire" its garbled signal long after the touch or stumulation is gone.
There are Health Pages that deal with what you went through. They are the one on "Paresthesias - Things that Go Buzz in the Night"
http://www.medhelp.org/health_pages/Multiple+Sclerosis/Paresthesias---Things-That-Go-BUZZ-in-the-Night/show/378?cid=36
and
"Nerve (Neuropathic) Pain - a Primer"

I hope these will explain your fierce reaction to your husband. It is important that he and you realize that your reaction was to real pain but NOT to real injury. He surely thinks you over-reacted and may, inside, be afraid he actually injured you. These paresthesias and allodynia feel like sever injury, but actually do no real harm.
As an overall answer, MS patients may have abnormal responses to pain in some places, the places where the sensory nerve signal have been changed by areas of demyelination. But, other than that, they may actually have a higher ability to withstand pain, because they deal with so much. On the other hand, those that need to use narcotic pain maeds may, indeed, have a lower threshhold for pain. So, the best we can say is that we certainly can have "messed up" pain and sensation responses.
I hope this helps both of you understand what happened.
