5 weeks post op, I have redness and pain on my interior thighs after Liposuction. Is this normal? (photo)

I had lipo and a tummy tuck on 4/10. Lipo to flanks, outer thighs and inner thighs. lipo sites were sutured closed. Need to note that my compression garment was extremely tight. At my first post op visit my legs had red, warm, and painful patches to inner thighs. Was placed on several rounds of antibiotics, culture negative. 5 weeks later, and areas have not improved and are still sore. The color has now changed to a darker red/brown. Any ideas what this is? PS states has never seen this
