Thanks everyone! As a quick update, Titan's MRI came back clear of a herniated disc or any further spread of his cancer so that is great news! It showed swelling and inflammation of muscles in his neck and near his spine, leading to his pain. We are on a new pain management regimen which includes 600mg of gabapentin 3x a day, a muscle relaxer 3x a day and his usual carprofen of 50mg, 2x a day. We still have trazadone if we need it from a sedative perspective, but will avoid using it due to his adverse reactions. 

He will be on even greater bed rest for the next 2 weeks while he heals. We are hoping we can get him rested up and healed quickly so he will be back on his 3 feet and can continue his adjustment to his new way of life!

We are glad it wasn’t anything worse as well! The muscle relaxer is diazepam. We have been going to Ohio State University vet hospital since his original diagnosis two years ago. They have taken such great care of us. His oncologist has become like a friend and even while being there for this muscle strain, called to check in on us and looks in on him frequently. We have received  best in class care with them and are very thankful we are local to such a great university (biased bc my husband and I are both grads) and veterinary clinic/hospital.
