Worse back pain after physical therapy?

I finally decided to go to physical therapy for my back. I was having lower back pain for 2 weeks straight and turns out I have a bulging disc on my lower back, the pain went away but I still have other back problems like upper back pain when I wake up or when I clean. The therapist decided to work on my lower back first even though I wasn’t having pain at the moment and another day for my upper back. He did some electric stuff I forgot the name and some massages. well since then my lower back is in pain!!! I feel like he made it worse 😟is that possible could he have made it worse? It honestly felt like that electric feeling you get in your spine when you get an epidural during labor while he was massaging it and from there it just started hurting the whole day 🙁
