Yes, it is advisable to follow your doctor's recommendation to step up to Maxbalin ER 100mg. Your symptoms suggest nerve compression, such as Carpal Tunnel Syndrome, from repetitive computer use. When a starting dose of Pregabalin (75mg) provides only temporary relief, increasing the dose is a standard clinical step to achieve better pain control. Please take it exactly as prescribed. Since your pain is triggered by computer use, I highly recommend adopting ergonomic wrist supports, taking frequent stretching breaks, and considering physical therapy for long-term healing. Inform your doctor if you experience side effects like dizziness, severe drowsiness, or swelling.
