Im 27 years old, I am 5 3 and weigh 8 stones. For the past week I have had chest and back pains which hurt whenever i took a deep breath. I tried to take pain killers and use balms to reduce pain but nothing make any difference. I eventually when to see the doc who said it was a sports injury and gave me ibuprofen 400mg and codine. The pain has reduced hugely in past 2 days, but now Im finding myself in immense pain when I get hungry. The pain is in my back mainly and it is so painful that for the past two days its caused me such pains in my back and mid-chest that I cannot get rid of it by doing anything other than eating. This has meant waking up at 5 am just to eat and then go back to sleep !! Its insanely messing up my routine but it is so painfully unbearable.
