Every state's WC system is different, but in CA, TTD is much higher than even if I were to be rated out at 100% (which is darn near impossible.)

If you have been receiving TTD, SS should run the formula and pay you until that changes. You'll need to have WC mail them a report of all payments made to you. When you settle with WC, SS will rerun the formula.

I have an active WC case, currently receive TTD, and SSDI as well. It took an insane amount of time to get all my backpay and children's benefits, and the SS monthly checks took 6 months to start after approval, due to the WC complication, but I've never heard SS claim they'll force you to wait until after you settle with WC. What if it takes you 10 years to settle with WC? Unless you're in a state that has a limited period of TTD, there is no sure way to predict when you'll close your WC case. There was a woman on the WC forum recently who just settled her WC case after 20 years.

If your doc claims you're still TTD, you may be able to get new training during this period. (Check with your attorney.) If you have any desire to complete a college degree, this would be the ideal time to pursue it, even if you can only manage going PT. The more education you have, the more money you can command per hour. You might realistically only ever be able to work a few hours per day. Or you may go into full remission... It's best to plan for the worst case scenario.

Since you have a background in sales management, I'd check out business to business sales jobs that have a national database, so that most of your correspondence would be by phone. This would keep you off of your bad limb, but you could work in an office and have the companionship of your coworkers. I'm not sure how much of a factor environment contributes to your escalating pain levels, but if this is an issue, make sure your doc has addressed it in your work restrictions. If you rarely leave your home, the vibrations, noise, cold, etc.--might be something you haven't factored.
