Thanks for posting your query.
The pain in outer side of the leg while walking can be due to-
1.Experiencing pain in legs specially on walking indicates a vascular problem most likely.The pain may be caused by claudication caused by peripheral arterial disease (PAD), narrowing of the arteries that carry blood to your leg muscles.
2.Peripheral neuropathy- This can occur from direct nerve irritation
or from a medical illness like diabetes
, thyroid imbalance, etc.Chronic illnesses like alcoholism
, cancer, and vitamin deficiencies may also result in nerve pain
that often affects both legs. There are some illnesses that cause leg weakness that may be associated with complaints of leg pain, like Guillain-Barré syndrome and multiple sclerosis
3. Muscle pain: Muscle pain or myalgia
is a common cause and may be due to overuse (mild trauma) or associated with the generalized aches and pain of an infection.
4. Muscle cramps: Muscles may cramp, causing significant pain. This may be due to a lack of stretching or an imbalance of electrolytes in the bloodstream. You need to get your serum sodium, potassium, calcium and magnesium
Since you have already been diagnosed with vitamin D deficiency, it is best to get your levels checked again to know whether the deficiency is persistent.
Getting your bone mineral density evaluated will give you an idea regarding the calcium stores in your body which is a common cause of leg pains in perimenopausal women.
