Lower leg and foot pain with body weakness, poor sleep, and a history of IBS in a 47-year-old can have several overlapping causes â the most common being
Vitamin B12 deficiency (which causes peripheral neuropathy-like leg pain),
Vitamin D deficiency, or poor sleep causing generalized muscle fatigue. IBS itself can also affect nutrient absorption, making deficiencies more likely. Restless legs or early peripheral vascular issues are also worth considering.
