Sounds like you are a hypocondriac (only joking). All you have done is tear a muscle. You will get over it, in a few days, don't take ibuprofen as this can cause internal bleeding of the muscle. But use Ibuprofen gel on the main part of your arm. The reason your other parts are hurting is because you are having muscle spasms, due to the fact your arm is damaged. The best thing to do is put a cold compress on it then a hot one (Do not burn yourself) also go to your doctor and ask for some codine phosphate about 30mg should do! Take 1 to 2 every 4 hrs, but no more than 89 in one day.
Hope this helps
