Would using Topical Triamcinolone Acetonide Cream help my neck/chin lumps from recent lipo?

I had neck & chin lipo 4 weeks ago. I'm still quite sore & lumpy. I wear the head compression wrap at night now for a few hours. I've been massaging the lumps in my neck & using Arnica gel on the area. Would like to know if this Triamcinolone Acetonide Topical Cream I have might help?
