Four days ago I was prescribed Bactrim for Bronchitis from an Urgent Care facility. First couple days I had trouble sleeping, chills,headaches and nausea. Now on the fourth day I woke up with hugely swollen lymph glands. Almost bigger than the size of a quarter. Tender and painful too touch. Worried if I continue with the medication they'll only get worse. Going to stop medication before ten day requirement. Painful bumpy neck not so attractive.
