Sciatica can be very painful and it usually takes a few weeks before it gets better , which can happen as quickly as it comes on .
My husband suffered with it on many occasions even before he was diagnosed with Parkinsons , had a few since and found it very difficult to cope with .
Our Gp prescribed a low dose Amitriptyline , the antidepressant also used for nerve pain . As well as helping to sleep better he hasn't had sciatica since .
