I just had an infection that developped in a lymphagitis on sunday. I was put on antibiotic first directly in the vein (wich a receive 3 doses) then been on pills antibiotic since tuesday. The red line from the lymphagitis as disapear since my second dose of iv antibio. The thing is, I ve been feeling weird since. No big shivers and no fever, but I feel like i m falling sick. I ve since developped feelings like a cold. I sweat a lot and sometimes feel cold. I feel like I m developping a flu. My question is, should i go to ER? I m kind of afraid this could turn in a blood infection. I should mention also that 6 years ago, when I was 26, I had zona. Don t know if it helps.
