Not a fan of Neulasta. I had horrible pain in every bone and joint in my body the day after my shot and 2 days after my first chemo. It was horrible. I couldn’t walk due to the pain in my feet and couldn’t sleep. My Oncologist did not make me have it again, and my labs were fine without it. 3 yrs after chemo, and I still have some joint pain, neuropathy in my feet and brain fog. Hope your shoulder gets better.
