Had breast reduction in 2019, still feeling tightness on my chest when I lift my arm. What should I do?

Halloween of 2019 I had a breast reduction, i was a 40 G a d i just wanted to go to a DD. I woke up from the surgery .. and i hated them and could not stop crying, i was flat .. completely flat, they told me within 2 days are so they will eventually be at the correct size and nothing i spent almost 2 months fully healing because the right breast wasnt stitch completely. Til this day im still feeling the tightness on my chest, every time i lift my arm a d wake up from sleep, scars are horrible
