I have just finished a series of injections for this very issue. I have found consistently that symptoms are increased for a period, for me 1-2 weeks, feels kind of like it's just from the increase in local fluid and pressure, mild bruising, etc. We've been following behind with saline to hydrodissect the tissues which are super tight. After that it has settled and made improvements. Definitely watch for atrophy, my injection sites looked good till last one and now I've a got sunk discolored area. Should resolve over time....
