hi the most likely scenario is that the body will form a small pocket around the invader and isolate it. if it's biodegradable then it should decay over time otherwise you'll carry it around for the rest of your life. do hope this helps. good luck
foreign objects injected into bloodstream. i accidentally had lint or a food crumb or fiber or something that was in a saline flush through my central line ( pic / port ). what happens to you when a foreign object is in your bloodstream? i know about air emboli and such but something like a hair or a fiber; what happens then? . i've been doing iv treatments (hospitals and in-home care) for years and rarely get concerned or don't know what to do. i'm really hoping someone has any bit of advice or experience they can share. i'm scared!
