I am 22 yrs old and I have difficulty in doing exercise as I can't continue my exercise on next day due to muscle soreness and weakness . So I take opinion from online doctor and he told me to rule out vitamin d and b12 and serum calcium ( vitamin d is 6.09 Ng/ml, b12 is 165 pg/ml, serum calcium is 10.1 ) . After seeing reports he prescribed ( Tayo 60k tablet once a week , shelcal 500 once a day and b complex once a day ) for 1 month duration....so is it ryt medicines according to my reports??? Plz I need Ur advise ? TIA
