Can't lift my arms all the way 10 days after Smart Lipo on arms and lateral chest (bra area under arms). Is this normal?(photo)

Some tenderness and swelling is normal after your procedure and will resolve with time. Lymphatic massage, compression, and RF treatments like venus legacy do great post liposuction and are essential for improvement/healing. If you remain concerned, I recommend following up with your Doctor. Best, Dr. Emer.

The lumpiness, swelling, itching and hardness after a surgery like you had typically persists at least 8 weeks after the surgery then slowly goes away. In my experience, daily massage of the hard areas makes the biggest difference in getting rid of it sooner rather than later. Staying away from salt will make a big difference in swelling. It can easily take 6 months or more to see results. Be sure to keep any scheduled follow up appointments you have with your surgeons for his evaluation and advice. Hope this helps!

This could be normal, but I would encourage you to contact your surgeon and have them evaluate you in person.  Based on the picture, I do not see signs of infection or other issues.  However an in-person exam is the best.
Good luck to you,
