I'm sorry to hear about your joint pain, especially in your back and knees while driving. Joint pain can be quite uncomfortable and may affect your daily activities.

For relief, a medication called Indocap Capsule is sometimes used. It helps reduce pain and inflammation by blocking certain chemicals in the body that cause swelling and discomfort. However, this medicine requires a doctor's prescription and should be taken only under medical supervision because it can have side effects like dizziness, stomach issues, and increased risk of heart problems or bleeding. It is also important to avoid alcohol while taking it.

In addition to medication, here are some general remedies you might find helpful:

• Apply warm or cold compresses to the affected joints to reduce pain and stiffness.
• Gentle stretching and strengthening exercises can improve joint flexibility and support.
• Maintain a healthy weight to reduce stress on your knees and back.
• Use ergonomic supports like cushions or lumbar supports while driving to reduce strain.
• Avoid prolonged sitting or driving without breaks; take short breaks to move and stretch.

Since joint pain can have many causes, including arthritis or injury, I strongly recommend consulting a rheumatologist or an orthopedic specialist. They can evaluate your condition properly, suggest appropriate investigations, and tailor treatment to your specific needs.
