As Ninekphysio says, training will only make things worse with the rigours of depot but is right in that if you start getting it treated now then you should be fine!
If your not due to start depot for a year I personally wouldn't say anything until you have a clearer picture closer to the time. I did Pirbright with a split achilles tendon sheath which knacked ALOT and got it treated after so it's up to you really.
Main thing, whilst waiting for Physio is maintain whatever strength and stamina you have already by doing basic quads exercises, paying attention to the VMO and lots of balance type stuff ie 1 leg balancing, maybe invest in a wobble board.
ALL EXERCISES should try to be as pain free as possible for the moment.
It took me about 2 months to recover completey from Pattelar Tendonitis. The physio told me to run my foot over a cold coke can in the morning when my foot was at its tightest and do a thing called frictions, basically rubbing the sole of your foot. Worked a treat.
Also worth considering what caused the problem, for me i am virtually flat footed to insoles with a small heal wedge to change the arch of my foot.
I still get the odd twinge but only after a very long day on my feet or long run
BTW Hitman - amazingly when I tried to get an answer to your question I was met by a wall of slopey shoulders - I think its basically down to the doc on the day as the guidance is sketchy. Will keep trying - hope its improving anyway!
