Thanks for posting your query.
I understand your concern.
The continuous pain in the calf muscles can be due to-
1. Calf muscle strain
and tear - Usually due to overwork and overstretching of the muscles. Recent increase in leg exercises may cause these. Gradual increase in exercise and pain killers with mild symptoms.
2. Muscle ischaemia- associated with diabetes
usually. There is acute pain associated with it.
3. XXXXXXX vein thrombosis- comes last among the list of probable diagnosis.
4. Myositis- Muscle pain
is a common cause and may be due to overuse (mild trauma) or associated with the generalized aches and pain of an infection.
5. 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
You may get the initial physical examination, relevant tests and treatment done under care of 'Orthopaedician'.
