I tore my bicep lifting heavy objects at work with no training, how much can I claim?

While working on a building site I was told to move a lot of heavy objects, I did not have my safety card and had no manual handling training and wound up tearing my bicep, I had to go to hospital, was out of work for months and my arm still does not feel like it used to, how much could I be entitled to for an injury like this?
