9 days old 2 lower wisdom teeth removed. One side bleed a tiny amount where stitches are. These are showing no sign of dissolving. Told 7 - 10 days?

Give it time. If the area is clean and healing, don't worry. Follow up with the oral surgeon as scheduled, but call sooner if the area puffs up, has drainage or you get a fever.
Depends. The discomfort and stiffness can vary depending upon what type of extractions- bony/impacted, tissue impacted/ infection present prior to extraction, etc. If these symptoms persist, call the dentist/oral surgeon.
