two weeks ago I was diagnosed with strep throat. Got antibiotics, never felt any better, continued to have all the same symptoms (extremely sore and tight throat, headache, swollen glands, fever). About two days shy of finishing the antibiotics, I ended up with what my doctor said was angioedema of my top lip. She instructed me to stop the antibiotic and put me on another (Amoxicillin). Three days later I was feeling back to my old self, all symptoms gone. Yesterday, the gland on the left side of my neck started to swell and is tender, and I have a sore throat on the left side of my throat, headache and stomach upset, and feeling fatigued. I ve finished the Amoxicillin this morning. What s going on?
