Answers:
Jogging is rather high impact on your body!. The constant jarring and pounding of the ground can cause alot of stress to your legs and may even cuase backpain!. The results of the stress can lead to injury!.
I personally used to jog a couple of years ago!. I jogged10 kilometres every day for 1 month!. My muscles got tighter and tighter after every session and eventually I had a calf muscle injury that kept me out of work for 2 weeks and ever since, I have had less flexibility in my right leg calf muscle!.
Looking back after completing a fitness instructor course, I can identify a number of things I wish would have done differently!.
I recommend cycling for you!. It is low impact and the bike carries your weight, as well as providing a more comfortible ride for your back!.
But if your determined to jog and your doctor says its safe for you, then build up to it slowly!. Allow your body time to adapt to the strain by starting off walking for some time!. Around six months should be enough to strengthen your bones and muscles in the legs sufficiently!. Then start slowly jogging, and building up the time gradually!. For example, after having a light walk for 1 hour a day for six months, you start replacing 10 minutes a session with light jogging for 1 month!. Then the next month you increase it to 20 minutes!.
Also once your workouts get higher in intensity, then increase the rest time so that your body can recover from the stress!. Otherwise, like me, it will start to have a negative excercise effect on your body, leading to negative results, and injury!.
Also make sure you adequately warmed up, only do light stretching after your muscles are hot/very warm and also after sessions so that you'll be less sore and have more flexibility plus lessen the chances of injury in the future!.

Stretching
= performed after warmup or main excercise!. takes only 5 minutes
= Slowly stretch a muscle till you feel discomfort, but not pain or tingling!.
= Hold for 30 seconds each stretch!. Or longer depending on how much more flexible you want it to be and how much tightness you want to relieve
