They will probably give you a colony booster shot, usually Neulasta, to help bring your white cells back up after your next chemo. The drug has some side effects, most notably bone pain because it stimulates your bone marrow, which can make some people a bit miserable for a couple of days. It is better than getting infections. Your most vulnerable time is 7-14 days after your treatment.
Ask your onc on your pre treatment meeting if they intend to give you that shot. Many people--myself included--find a Claratyne tablet a day for 10 days, starting on the day before chemo-- helps with the pain. Which you may or not experience.
Phhhftt, this sTuff is so exhausting on many levels.
