Myofascial pain and trigger points from flexor carpi ulnaris should be the next spot you look at after working with flexor carpi radialis. The referred pain caused by trigger points here will be similar to flexor carpi radialis but in my experience the pain runs down towards the underside of the outer hand and to the middle to pinky fingers. If you believe you’re having carpal tunnel syndrome, check this area.
I find the forearm extensors to be the first stop in dealing with carpal tunnel syndrome but I recommend looking at these two trigger points in addition. Spending time at a computer is something most of us will continue for a long time so regular maintenance is a must. When you work the trigger point, go slow, it can be tender. You’ll find it exquisitely painful then hang out, breath and see if it releases.
