I'm 3 weeks post op. 385cc silicone, round, under the muscle. About 4 days ago I started having body aches / chills. Took my temperature today, it was 100.2 F. Also, when the chills started I began having a lot of pain in my back and a lot of stiffness on my left side. Feels like a knot in my back. Unrelated? I'm really confused. Saw my PS today and he thought everything looked great. I was unaware of my temperature until later.
