Tightness on jaw joint after Botox masseter reduction procedure, is it normal? When & how can this swelling & tightness go away?

31/F/Asian did Botox masseter reduction yesterday.150 units 5-6 points each side. Left masseter is naturally slightly bigger than right. Aesthetician told me she adjusts the points accordingly. Post injection, I feel tightness on my right jaw when I try to open/ close my mouth. Both sides are still little swollen 15hr post injection on injected area. Is this normal after Botox masseter procedure? When will this swelling & tightness in my right jaw joint will go away? Left side is perfectly fine.
