Many times patients complain about the pain in their back, neck and wrist while driving a bike. This happens because of the wrong driving habits and the poor condition of your muscles physical fitness and the broken roads.
Whenever you drove the bike in a broken road your body gets a big amount of pressure on all your upper body that includes your wrist joint back and neck and repeated shock makes your muscles weaker over the time and it started giving you pain. The repeated trauma can be minimized by using correct biking gears to protect your joints and driving the bike on the road, not off the road and skip the holes. The neck is already balancing the weight of the head while driving if your helmet is not of the correct size and weight it will give extra force on your neck to hold and over the time it will start to give problems like pain, headaches, stiffness etc.
Do always check for correct posture while driving. Try to do small stretching of your body before and after a long drive. And if you feel any problem do consult your Physiotherapist/Doctor before any small problem comes in a big picture. Always remember "Prevention is better than cure"
