Pain when bending over?

7 weeks post op under muscle (34B to 34D). All good no pain. recently I did a workout (high knees for first time and planks) now when I bend over I feel a pain almost like it's under the implant. when I push my implant up from bottom of breast i feel pain at the top. when I was massaging I feel pain all along where my arm meets armpit and along the top where the top of implant is and chest bone is. I have vaped sometimes in the last couple weeks (nicotine) and worried about CC.breast is sofT.
