Post op day 4 BBL, very strong pain on one side??

So my right cheek, the underneath part hurts so badly. I have used this leg more for getting in and out of bed, and my SUV. So I'm wondering if I just over worked it? It does seem slightly more swollen than my left side. It almost feels like a constant muscle spasm. Is this a normal part of healing? No redness, or heat. I'm assessing myself as a nurse. No signs of DVT in my lower extremity either. I did a lot of walking yesterday also. Thanks!!
