Over the weekend I was on a friend's speedboat, when he came about really quickly and with no warning. I was thrown against the side of the boat very hard, hitting my chest, just above my breasts, on the edge of the boat. The pain in the left-hand side of my chest was severe for a couple of days - I had to hold my hand on that side up to my shoulder to release the pressure, but as the bruising came out and the swelling went down, the pain there has eased. However, for the last two days, I have suffered some extreme shooting pains in the centre of my chest when, for example, pushing myself up into a sitting position in bed. Also, I have a constant feeling that there's something trapped in my throat around that area, similar to the feeling you sometimes get from swallowing a tablet and having it 'stick'. This feeling is compounded by taking a deep breath, although this only occasionally causes any actual pain.
However, the pain, when I do get it, is very similar to that I experienced a few years back when i cracked a couple of (fairly low) ribs.
I'm travelling at the moment so can't see my regular doctor, and I don't speak the local lingo. Any ideas what this might be?
