Regarding your question about the correlation between forklift use and lower back pain, there is indeed evidence supporting that prolonged forklift operation, especially on uneven surfaces, can exacerbate back issues. Terms like "dock shock" and "whole body vibration (WBV)" are well-known contributors to lower back pain in such environments. These conditions cause repetitive jolts and vibrations that can strain your back muscles and spine.

To help mitigate this discomfort, I recommend investing in a high-quality gel seat cushion for car & office chair. A gel seat cushion can provide enhanced support and distribute weight evenly, reducing pressure on your lower back during long shifts on the forklift. For relief both at work and in the office, you might consider these highly-rated options:

These cushions are designed to alleviate discomfort and support proper posture, making them ideal for preventing and reducing back pain. Using them consistently could provide significant relief and improve your overall comfort during work.

I hope this helps and wish you the best in finding relief for your lower back pain!
