1. Disc bulge in upper spine is only usually under an accidental trauma!!! Please confirm if any.
2. You seem to be working hard to time your body,hence the physical activity stressed. I presume weight loss is the concern here.i also read you are 27/female.
Heavy breasts could also mimic disc bulge symptoms ,due to weak back muscles.
3. Gym is a controlled closed environment body workout and dancing and cycling is an open body activity.
So you can opt for any workout but after getting actual diagnosis done.
