Issues like skin paleness, lip cracking, yellowing of the eyes, involuntary eyelid twitches, dark under-eye circles, and shifts in vision are common indicators. Identifying these signs promptly allows for early diagnosis and treatment, which is essential to avoiding long-term nerve damage and other severe health issues.
