... has improved slightly but nothing significant. My great concern is my swollen lymph nodes that are behind my ear... Towards my jaw. There are a cluster of them swollen. My lower back aches more than ever and I just don't feel right. I had a Cbc drawn and everything is normal. Why would my lymph nodes swell if there is no infection. I'm on a course of abx just incase but three days in not a single change in Size. I have frequent headashes and I'm not able to sleep well.Obviously reading more into the drug has been panicked. I'm usually pretty healthy... And never had these nodes swell not even when sick. I'm not sure if these are related to the drug or if it's something else
