Back pain recap

Almost 20 years ago I was injured in a car accident when I lived in LA, ending up with neck and back problems, nerve damage in my left arm and other orthopedic issues. So, when I began to experience back pain and leg pain in May, I discounted it as I am so used to living with chronic pain, assuming it was more of the same. it never occurred to me that it was cancer. Of course once I had surgery and was on pain meds my back and arm no longer hurt, or if it did, my brain was more focused on surgical pain. Then, having the port inserted, going through chemo, on steroids, my back was the least of my problems and I did not focus on it. Perhaps the steroids also lessened the inflammation and irritation so less pain? Now, 70 days with no chemo and about 65 days with no steroids, my back, neck, arm, all are aching again, especially my lower back as I sit or lie down and get stiff, like I used to. Can't decide if it is good or bad, or have the old familiar back, or worried that if cancer returns I will not recognize it again.
