Judging by your photos, a scar revision may significantly improve the appearance of your arms. Now that the scars have had the time to relax, they can be removed and closed with less tension than the initial operation. I recommend consulting with a board certified plastic to see if this would be a good option for you.
Thank you for your question.The best thing to do would to be evaluated in person by a plastic surgeon to discuss your options. The photos are not the best, so it is hard to make a determination for you based on them. Scars can always be revised, and Im sure there are options for the band you have on the arm. Good luck.
