I work in the IT industry and recently have been getting severe neck and back pains along with head aches. I also wake up with body ache in the morning. I clearly feel my foot has an ache in the morning. I do not work out and lack any kind of physical exercize from my daily routine. I feel weak most of the time and feel exhausted by the time i get back home. I had recently done a blood test and I was found to have a vitamin D deficiency for which I am taking supplements now. Please suggest.
