Pain in both legs from the knees to the toes for such a long time can happen due to several reasons, most commonly nerve-related problems (like irritation of nerves coming from the lower back), poor blood circulation, vitamin deficiencies (especially vitamin B12 or vitamin D), or joint and muscle issues. Since oils have not helped, it suggests the cause may be deeper than just muscle fatigue. Because your symptoms have been present for a year, it is important to get a proper check-up; your doctor may examine you and suggest tests such as blood tests or scans to find the exact reason. Treatment depends on the cause and may include medicines, vitamin supplements, physiotherapy, and exercises to improve strength and circulation. In the meantime, avoid long periods of standing or sitting in one position, keep yourself active with gentle walking, and maintain good posture. You should seek medical advice soon, especially if the pain is worsening, associated with numbness, tingling, weakness, or difficulty walking, so that the right treatment can be started and further problems can be prevented.
