Does keloid return after steroid injection?

It may. Keloid scars are very difficult to treat. If good response from steroid injection, result may be permanent. Unfortunately keloids occasionally recur and require additional treatment.
?Steroid Injections? All scars are permanent --- keloid is a scar that might be growing and/or hard and/or lumpy and/or itchy --- steroid injections may reduce the lumpiness, and itching and may stop the growth in most patients. But the basic scar will always stay even after the steroid injections.
