I got knocked off my bike and my shoulder really hurts. Doesn't feel broken but do I go to the doctors?

I was cycling through london, probably around 14mph and some idiot waiting in a traffic light queue just opened his door without looking. I had no time to break or swerve. I managed to move the bike out the way but took a big hit to my hand and shoulder. I managed to cycle the rest of the journey and then another 14 miles later but in quite a lot of pain. I then had some ibuprofen when I got home and a nights rest but it still REALLY hurts. Doesn't feel remotely broken or dislocated and doesn't appear too swollen but should I make the 2 hour wait in the hospital or go to the doctors or just rest up??
