There is another wicked undesirable effect that goes along with the decreased strength: muscle atrophy. This is a serious side effect to nerve impingement and crush injuries.
I have a very bad lower back/left shoulder injury that has caused pronounced pain, loss of strength, and muscle atrophy past the injury/impingement point and it plays havoc with my goals.
Achilles is a good product (all of the Antaeus products are highly interesting). In a few weeks I will be releasing Nerve Restore through EvoMuse. This is a very innovative design that I formulated to help my own problem. It increases nerve amplitude and velocity, increases strength, helps support myelin structure, ablates discomfort, and counters the atrophy that accompanies that chronic reduced nerve signal.
For pain caused by sporadic, random firing of the nerve, this should help immensely. For the muscular seizing, that's a tougher one.
