Hi Phil,
Things should start to settle down soon mate, once the bruising comes out I found I was soon on the mend, think it took me about two days to make it to the pub... and three days to make it home again
If you have the metal staples in as opposed to stitches then only charge for short periods till you are shot of them because they do get hot, also they do increase charging time and stop you getting a good contact. If you have stitches then ignore that last sentence.
Hopefully you will soon be feeling yourself again...... err yeah
