My numbness has been a quasi permanent states with only a handful of days in the last 1.5 years where i felt almost 90% normal, maybe like 4 days.
It is improved by:
Heat
Long walks
Cialis (not always)
Relaxation
It worsens after:
Stress
Internal massage (to relieve cpps symptoms)
High intensity exercise (which redirects the blood to the core from the extremities)…
Just an observation. I am not saying circulation is the cause but it is interesting that it correlates with this. Maybe the numbness is felt less (more) when circulation is good (bad).
