It sounds like you lead a healthy and active lifestyle. Great job on alternating your lifestyle to keep healthy.
On your first post, you said that you were given Lyrica and told to come back in 6 months so I assumed you were just prescribed it either now, or 6 months ago. The headaches and sleepiness from the Lyrica doesn't sound good, and it looks like pins and needles is also a side effect. Could that be causing or exacerbating the problem? Looking into an alternative is a good idea.
Hope that helps. Keep us updated if you figure it out!
