I had orif surgery back on July 30, 2015, open wound on foot. It healed after 60 days and two days later my foot started leaking pus out of a pimple like bump on the part of the incision I had no problems with. I came to er and had to have surgery to remove it. Two days after surgery I felt super dizzy fever 103 and I was out of it. My Bp was low in er and I usually have 110/80 religiously. It continually dropped to 67/27 or something like that and it started to go back up and stayed from 105 to 108 and have had bad headache and indigestion for days. Now three days after the episode I now have Bp 140/71 and I have felt bad all day. What could cause this? Also my legs have swollen size of tree trunks.
