It is very early to say about your prognosis; it is better to wait and do regular check-ups as directed by your doctor.
Next, it is normal to have swelling of your eyes due to accident crush. All your body has gone under crush-stress
and you are now experiencing the consequences.
Usually, it would need up to 1 year to clearly see the improvement. Meanwhile, frequent scans and check-ups are mandatory to evaluate your health status to prevent severe problems in the future. You should follow your doctor instructions.
I could suggest to have some rest, do not stress yourself about the cure. Generally, analgesics, or local treatment are enough.
Hope it helped!
