    I thought sometimes cautions were so excessive they have made me fearful and now uncertain. I understand it takes a balance but for me it left me so anxious as I became untrusting of my body as the cautions stayed same whether in week one or week 10 in recovery.

    He explained the injection. He’s very knowledgeable. Told me what to expect and when, suggested when to come back as needed.
