2nd weigh in and back issues

So i lost 1.4kg's at my weigh in on monday thats 2.1 in 2 weeks... Super happy with that. Hoping to start exercising again soon but have been diagnosed with having a disc bulge and a protruding disc in my lower back so will be off to the drs next week to see what kind of treatment path to go down and what im allowed to do at the gym
