Long-lasting discomfort behind the knee could be caused by venous problems, muscular strain, or Baker's cyst rather than just nerve pain. Give up self-medication and be checked out; if pain or swelling worsens, a Doppler or ultrasound may be required.

Meganeuron OD Plus is not used only for vitamin B12 deficiency, as its combination of Alpha Lipoic Acid, Benfotiamine, Biotin, Folic Acid, Pyridoxine Hydrochloride and Methylcobalamin supports overall nerve health and is commonly prescribed for neuropathic symptoms such as numbness, tingling, and nerve pain. Hence, its use depends on a doctor's assessment and is not restricted to isolated B12 deficiency alone.
