Oh, Anuradha, not a good thing -- but if you got antibiotics while it is still local, perhaps that will stop it early!
My husband developed an insignificant-looking rash on his shin -- the next day he had erysepilis -- sudden fever, nausea, vomiting, severe diarrhea. He landed in the hospital for ten days, his leg swelled to twice its size, he had dehydration, irregular heartbeat due to electrolyte imbalance, elevated blood sugars (and he is really PRE-D, not T2, yet) followed by 7 days of IV antibiotics through a PICC line -- it was quite the drama. We think it was MRSA as he ended up getting FIVE antibiotics to finally stop it, and Kansas City has or had at the time the highest community-acquired MRSA rate in the US!
I am glad that you got antibiotics early, and I am truly not posting our story to alarm you, but so you are aware, if there is sudden onset of symptoms like his, head to a hospital! He really had no idea what he was dealing with and would have saved himself a LOT had he gone in sooner.
