Do these lipoma removal stitches look un-healed and/or infected? (photo)

I'm supposed to get the stitches (above my tibialis anterior muscle) out in the next 1-3 days and I'm nervous that they're not ready to come out & are infected. I'm mostly concerned with what looks like a blood blister on the right side of the incision & the tender knot below the incision. It's still red & sore, but doesn't feel warm/hot and is dry. Does this look infected and unhealed to you? I've been using an antibiotic ointment and taking cephalexin twice a day.
