Since the last six months, I suddenly developed severe pain in both the legs. It arises from the thigh, goes to the calf, and finally reaches the heel. I am unable to go up the stairs or use the Indian style toilets.
From your description, I feel that you have patellofemoral compression pain, which gets worse on going up and down stairs. After a period of rest, you may feel severe pain in the the knees, but as you walk the pain will ease.
I suggest the following:
Take Voveran SR (Diclofenac) 75 mg twice a day for two weeks.
Under the guidance of a professional physiotherapist, do quads strengthening exercises of the closed chain type, hamstring stretches and core strength exercises.
Avoid squatting or using the Indian style toilets.
