Thank you for asking you query.
From the information you provided your Body Mass Index is 28 approximately which classifies you under overweight category. Adding to that if you have been physically inactive, the panting you experiencing is explainable.
Physical inactivity and obesity can lead on to decreased aerobic capacity and as a result when you run for a short distance you can become breathless.
There is no need to worry though. You can exercise and if you keep doing it, the aerobic capacity will pick and you will be back to normal.
The aches and pains you are having seems non specific and is not suggestive of anything now. I recommend you to get medical help if the problem is persisting.
Hope this helps.
