I strained my back moving my daughter's trunk for summer camp. I saw my orthopedic doctor and he took some x-rays that didn't reveal anything. He told me it was muscular and told me to go get some PT for 4 weeks and that if it didn't improve that after 4 weeks he would prescribe an MRI. I also saw a Chiropractor who said that my back wasn't strong enough for physical therapy yet and I should allow her to perform some ultrasound therapy and some other therapy to help heal my back for 2-3 weeks before I start physical therapy. I feel like everyone is biased so I'm not sure who to believe. Have others waited before starting PT to allow the muscles to heal?
