Nearly almost 3 years, during my job days, in every 8 months I got weakness, headache, not able to focus on screen so I take off for 4-5 days and when I gain my weakness recovery then start work. For almost recovery it takes 1 month when I focus a lot on my diet. Whenever I go to a general physician they write a blood test, urine test, and typhoid test. And every time only hemoglobin found less like 10.5 and nothing more. Only that was the reason or stress due to work ?
