What is sciatica anyway? I'm really not sure what this means anymore.
You are right, the name sciatica is casually thrown around by medics who can't be bothered to look more closely, and sufferers who don't 'yet' know the difference. But it is based in biology, it's just that you need to correctly identify the symptoms and locations as you trace them through the 'autonomic nervous system'.
Real 'sciatica' will always involve either damage to, disease of 'or' impingement of the nerve strands as they travel down the spinal column or as they exit the spinal canal, usually at the L4/5 lumber level or as they travel down the legs.
These nerve strands could experience these problems any where between the sinal column, foraminal openings (nerve root exits) and feet and travel down the right, left or both legs. Right sided nerve strand impingements will affect your 'right leg' and visa versa 'or' both legs.
Because these strands do not have 'pain recepters' down the length of
the strand (only at the ends) when the brain detects a pain signal caused by the impingement, lets say at the foraminal opening, the brain becomes confused and 'fires' locating signals to try and find the source of the pain
signals, this is why we get 'transfered pains' in the legs.
This phemominum is similar to the 'phantom limb pains' experienced by amputees after they loose legs and arms. The brain ''cannot compute'
so it goes looking for the the missing recepters. (for info on this look up 'mirror box').
Also, sciatica from the L4/5 level will usually transfer pains down the front of the legs and groin, the lower L5/S1 issues usually travel down the backs of the legs instead. Of course, you will have both if you have double level issues.
I hope that helps
Best wishes
