Saturday, I got the chills very bad, took my temp and it was 101.5. I was vomiting and sleeping a lot, felt super cold (even though I wasn t) all day. Was not as bad, but still sick on Sunday and did not shower. On Monday, today, I felt 100% fine, but when I went to take a shower I noticed the top of my right foot was really red and very swollen (swelling for me is normal as I am a paraplegic, and also therefore cannot feel my foot) and has lots of red bumps all over it. This is only on the top of my foot and no where else. This has never happened before. I also, due to this flu or whatever, woke up this morning with 2 cold sores.
With the fever, chills, and the swollen red foot, I would be very concerned about the possibility of cellulitis, an infection in the skin. Your body has been stressed from this, and that is why you developed cold sores, which are caused by a virus that becomes activated when your immune system is under stress from infection. This is something you need to have checked by a doctor right away, even if you are feeling better. The lack of feeling in your foot makes it difficult for you to judge how serious this could be. The infection could spread and get into your blood, so It's important to get it diagnosed and treated right away. Hope this helps.
