I was diagnosed for "Muscle Spasm" a while ago for my lower back pain. The pain went away for about a year and then came back again. I had a blood test taken and found out that I am deficient in Vitamin B12 and Vitamin D3. I am taking medicine for it.
During this 1 year I have gained weight, and now am 12-16 kg overweight. I have been trying to go to gym and controlling my diet, but whenever I run (on a treadmill) my back starts feeling sore. The soreness goes away in a day or two if I don't exercise. I am doing some stretching exercises, but I need to lose weight which is why I run.
I am a software engineer by profession so sitting long hours is a part of my job. Any suggestions on what I could improve my weight loss?
