Is this lump on lip from filler or swelling after Restylane? (photo)

Lip filler bumps is fairly common after filler.  The bumps can occur early on and many settle down.  Although massage after filler is considered a mainstay, beware that massage can drive the filler into another location if done too early.  
Reasons for bumps after filler:
Technique- Filler may have been used too superficially or wrong type of filler
Mouth movements- In some patients their movements can promote the accumulation of bumps and an alternative technique can be advocated.
Treating lip filler bumps:
Observation +/- massage-  Should be done for almost all lip filler bumps for 2 weeks.  For our patients we usually advocated massage after 48-72 hours to let the filler settle into place.
Reversal- A reversal agent can be used such as Vitrase to dissolve the filler if there is a large obvious persistent bump
Additional filler- An expert filler injector can used improved technique to mask the lip bumps.
The application of lip filler is very technical and should be done by an expert injector.

Best option is massage and waiting it out as you stated. Also returning to see the injecting doc would be advisable..// 

As it is still relatively recent since your injections I would recommend waiting for the swelling to subside in order to see whether it is related to the swelling or not. Once the swelling subsides, if the lump is still there then revisit your injector.
