Sd card is hot

My micro sd card is getting relly hot now when I plug it in to my computer. I use it for my phone but I add stuff from my computer all the time. Last time I put it in my computer and added some pix then put it back in my blackberry it would not read the card. So I put it back in my computer and now it wont read it there also the sd card gets very very hot while its plugged into the computer. Can any body tell me what is up with this sd card and if there is any hope recovering the files on it. I tried to format it and it wouldnt even let me do that. When I plug it in the computer says its not responding. Help please I need to recover these files!
