Scapula Pain

I have been having pain in my right side scapula area for 2 1/2 weeks now. I didn't injure it, well I fell in the army about a year ago and landed on my right arm but I don't think this would just start hurting now. It feels like bees are stinging me and severe cramping. When my boyfriend rubs it he says he can feel fluid and a knot in there, also when he rubs it, it feels like someone pushes their finger against my throat. It also makes a crackling sound. I get shocking sensations and my right arm/shoulder feels really heavy. I have a lot of cramping it feels like the pain is spreading and my shoulder is starting to stiffen. I did go to the doctor and he did and x ray and no broken bones, he diagnosed me with bursitis. He prescribed me steroids (medropack) and its not helping, getting worse. Help.
