I Have A Intrathegal Baclefen Pump, I Went To See

I have a intrathegal Baclefen pump, I went to see why was stopping before it went to my spine. The doctor said there was scar tissue covering the hole to my spine,so he pushed through the scar tissue and a few days later I got an overdose of Baclefen. Now the Baclefen makes me tighter. Is there a substitute for Baclefen
