Female, 20 - can you get lip fillers if you have chronic pain?

I have had chronic pain for 5 years (20f) in my back, hips and ischium and, while I have been scanned a variety of ways and seen a lot of drs, it is deemed to be a biomechanical issue. Note: I have had mild edemas in my hip due to this and have taken a 6-week course of pentoxifylline to help. Nevertheless, as this is a long exisiting form of inflammation, can this increase risk of complications like granulomas or body rejecting the filler as it is already experiencing this inflammation?
