I have severe sciatica. can you suggest something for driving a car?

Ice & lumbar support: Having had sciatica from a herniated lumbar disc, here is what i found helpful for driving: ice pack to the back before a long drive, ice after the drive, lumbar support pillow, tilting the seat forward but also reclining the back slightly, limit your driving time based on comfort level.

A chauffeur : Most often with a sciatica due to a disc herniation, sitting is uncomfortable, especially in a car. Sitting places 4x your body weight across the discs of your lower back compared to 2x while standing. However, the longer you are in one position you also add a static load similar to leaving a weight on a stack of newspapers for several minutes v an hour in terms of how compressed the stack gets.

Take Breaks: frequently. Unfortunately driving the car will aggravate your sciatica. if you can avoid driving for a few weeks, it might help while you heal. Otherwise try not to drive for longer than 30min at a time without taking a break. Suggest seeing a pain/spine specialist to see what options for treatment are good for you.

Lumbar support?: Is the sciatica from the legs or the lower back? Depending on the cause, one of these may help: 1) a foam cushion for the seat 2) lumbar support 3) physiotherapy 4) cortisone injection? 5) weight loss? 6) medication for sciatica nerve pain? may affect alertness while driving.
