For last 1 month I have a severe pain around my ribs - chest and back when I wake up in the morning. It lasts till I am lying on my bed and vanishes few minutes after I get up. When pain is there its too difficult to turn sides or even breathing deep. After I get up, I even go an play cricket. There is no problem in running and bowling which involve chest and back muscles. I consulted a doctor, he told that it might be due to Vitamin D difficiency. I took the prescribed multivitamin and calcium and vit d3 tablets for more than 3 weeks. He prescribed 2 injections also for vitamin D and B - weekly once. I took 2 of them so far. But there is no improvement so far.
