Sciatica, another trucker’s ailment alongside ulcers bad knees and farmer Giles.
I’ve had Sciatica on and off for about 20 years.
I take Ibuprofen for it, which relaxes the muscles, but when it’s particularly bad I have to take a prescription drug called Diclophlenac
. Excercise like walking helps, Simple stretches also help, eg. I put my leg on front bumper and press down on my thigh, which can hurt but it does relieve it while driving.
Sorry mate but if any thing like me it will be an on/off thing for years.
