Hi doctor, When work from is started i m getting back pain while doing office work. I used to sit on bed n whenever i go to bed for sleeping i feel pain. Sometimes i do exercise and walk outside to 1km  so that my body can relax but sometimes i can't sleep due to this pain so could u suggest is this due to bed issue or else i should buy table. Because once i had visited the doctor n they said go for walk n change the mattress may be than u can get some relief.  I take multivitamin medicine on alternate days to keep my body healthy .So just want suggestion from your end what to do .
