Piercing help?

J
I got my lobes (2nds) pierced about 3-4weeks ago and they almost felt healed but now the one on the left is swollen and hurts to touch. I haven't really been putting the spray on religiously as I felt like they were pretty much healed and the spray also seems to irritate my skin so I didn't like to use it. 
Today I have held a tissue with warm water/sea salt on it for about 10min.
Should I just keep doing that or is there any other ways I can heal it?
