manumom,
Unfortunately, it sounds like you have covered all the bases in terms of treatment options. As for the laser treatments, if they are helping significantly, continue them. But, if they aren't, then it's probably not worth the time, effort, and expense.
Of course, it would help if we actually knew what really caused the pillar pain. Then, the treatment could be directed at the source.
The only other thing that comes to mind, is that of deep massage. Some of the therapists have noted that patients who do deep massage of the base of the palm have some reduction in their pain, at least for a while. And, it is an easy thing to do, doesn't require any equipment, and doesn't cost anything.
Some patients combine it with a paraffin wax bath or hot packs, to warm up the tissues, to make them more pliable for the massage. But, it is not absolutely necessary.
Sorry, other than moral support and a little more tincture of time, there really isn't anything else to offer. Just the hope that this will get better with some more time.
Since one of the leading theories on the cause is destabilization of the bones/joints which make up most of the carpal tunnel, maybe the bones will eventually find a good resting position, quit moving around, and thus decrease the pain in the palm.
We can only hope.
Wishing you the best. Hope your problem finally works itself out.
Good luck.
