Sick Baby & Spots on Ears... Freaking Out!

 A week ago, LB ran his first fever of 100-103 during the night and we took him to the pedi the next morning (Friday).  He said it was an ear infection in his right ear and gave us amoxicillin and told us to do ibuprofen for the fever. Over the weekend, we saw improvement but Monday afternoon and through the night the high fever was back despite the ibuprofen.  We went back to the pedi on Tuesday morning and they tested for flu.  Thankfully that was negative but they changed the antibiotic to a stronger one.  Tuesday night his nose became really runny to the point of having to sleep (as much as he could anyway) sitting up to manage it.  I called the dr again on Wednesday and they called in claritin for that.  Today, he did not run a fever until after lunch and he was a little more active but we still have a nasty runny nose (not clear today either).  His pee diapers are a little less in amount but still changing about the same number (drinking lots of water/juice but not as much milk) and his poops are watery but the dr told us that would probably happen because of the antibiotics. So, he made some improvements today, but then I saw a dark purple spot in his right ear and a lighter one in his left ear.  I am freaking out!  Has anyone experienced anything like this?  PC told me not to G.oogle it and of course I did and I'm really freaking out.  Could it be something like a busted blood vessel from all the snot-sucking?  Poor little guy... PC and I are so ready for this to be gone and for him to get relief.  Breaking our hearts!
