I too have multiple craters after injecting C for three years. After awhile I just used my inner thigh and abdominal area...figured I had the most fat in those places. My neuro took me off of C last fall due to heart palps. I was off only for a few months when he wanted me to restart it. I never did but I didn't tell him. My heart palps are very minor now and I wonder if they were because of the C. I have been thinking about retrying it. I called the nurse at shared solutions who told me I was no longer eligible for the pt assistance program and the C has gone up to $4000 per month. Well, this put the kabosh on my even thinking about going back on it. My deductable is $5000, 20% copay after deduct is met and a $7000 out of pocket max. I cannot afford it. After doing some research I see that half of Teva's yearly profit comes from there C sales. It's all disgusting!
