Hi, I am 39 years male staying in Mumbai since birth. Since last couple of months I feel that I am lacking energy to do routine work at home or at office. I feel very tired & breathless even doing small things of daily routine. I feel that I always need to sleep due to this fatigue. Also I have stiff muscle & pain especially the calf muscles & the part below the ankle pains a lot. This is effecting my job and personal life. My height is 5.5" and I weigh 102 kgs. Please assist me as I feel I have some kind of deficiency due to which I feel tiredness anytime of the day.
