Sorry to read about your foot. Best to take care and not try to push things let it heal completely. The Boxster will still be there.
Have never been laid up since I've had my Boxster. Was laid up, confined to crutches, about 14 weeks after I broke my right leg in 3 places but that was years ago.
I've had gout off and on the last few years but even though my foot/ankle hurt almost too much to walk on I could still drive either car with no pain. Change in diet helped. Cut way back on meat even though I didn't eat that much meat before; and consciously making sure I drink plenty of water helped some more. Alcohol consumption was previously very very low and is now just one glass a wine about once a month above zero. Weight is good and with some exercise and diet I have lost around 10lbs.
Still would get a flare up every so often. Seems part of the reason gout became a problem is due to too many red blood cells which affects circulation. After all the tests came back negative for any disease behind this condition my doctor advised donating blood. Finally managed to donate a pint June 19th. This lowered my hemoglobin reading to 15.4g/mL down from 18.4g/mL and my hematocrit is at 46.1% down but I don't recall from its previously high reading.
Since giving blood I feel a bit better but the improvement is hard to describe. Best I can offer is I have a bit more energy. I have managed to up my meat intake -- still low by USA standards -- with no problems. Still have to drink plenty of water though. An alcohol intake is still going to remain quite low, near zero. My exercising will continue.
BTW, the Boxster clutch is not assisted. (Consider getting a 996 Turbo. Its hydraulic clutch is assisted and the assist is present even after the engine is shut off. There's an "accumulator" that stores pressure I guess that provides assistance to the clutch even when the engine is off. The clutch is easy to push to start the engine even though the car has sat a few days since last used. The downside is the accumulator can fail and the assistance storing ability goes away. The assistence is still present when the engine is running.)
Anyhow, stay off your foot until the doc says otherwise. I thought I was doing the right thing when I showed the doctor I could walk without crutches when I went to see him but he scolded me and told me to continue to use the crutches even though the leg felt tons better. He said he'd let me know when I could stop using the crutches. 14 weeks after the accident and surgery is when I finally put the crutches away. Even then it took some time before the leg came back nearly 100% and that was helped by physical therapy.
