A few years ago I was going to the gym, mainly to try and get in shape by doing some cardio and working on the machines. I have a desk job and was sent abroad for work almost 2 years ago. I have been experiencing slight back ache issues which are aggravated by things like wearing a heavy backpack or doing any intensive exercises. I got back to my home country earlier this year and had a really painful pinched nerve. I don't know if it is related to the back problem. The doctor referred me to see a physiotherapist and after 2 months it has mostly settled down. I inquired about an MRI but was told my case is not severe enough to warrant one. Anyway I feel both weak and out of shape now, yet I'm worried doing anything other than cardio or stretching could make things worse. What's the general consensus on lifting with back and neck issues? Is it dangerous or could it actually be beneficial if I start with much lighter weights?
