I had a total knee replacement in October 08 which was very successful. However, in January I came down with blepharitis. After 2 doctors, drops and antibiotics they now have stuck pins in the blister like sores that line my eyes and suggest I see a surgeon to have the under my eyelids scraped out. These blisters when broken, bleed and ooze. In addition to this infection I went to the dentist for cleaning. I took the prescribed antibioics before and all was fine. Than last week a filling fell out and when I went to the dentist he said my tooth had cracked in 3 places and was effecting the tooth on the side of it. He had to pull the tooth, which is the 2nd from the back upper molar. I have a full exam scheduled for next week. My question is are these infections due to my knee surgery, can they effect my recovery of my knee surgery or are they just different problems although? I know they said infections can be very dangerous.
