I've been able to feel my lymph nodes for as long as I can remember, they are rubbery, mobile and pretty small. Is this normal? I've had a rod in my arm for a year now, but I was spiked at a club 2 weeks ago. Since then I've been vomiting pretty much every day, I constantly feel sick (worse at night) and constipated. Is this normal or has it spiked because of broken my rod?
