I Have Dermatomyositis, Scleroderma & Reynauds. Is Botox Safe? Also Have Spinal Injury.

I have undifferentiated connective tissue disease and though dermatomyositis (gottrons papules on hands, muscle & joint pain, no muscle wasting) has been confirmed, reynauds and scleroderma are also suspected on hands and elbows. Is it safe for me to have botox on my forehead, crows feet and between eyebrows? I have also had 3 spinal operations on my neck and take 40mg omeprazole, 8 x paracetamol, 600mg pre gabalin, 25mg nortriptline daily for nerve pain.
