Is There Any Side Effect From Injectable Dexamethasone While On Warfarin?

I am suffering from 2nd shoulder rotator cuff surgery in same shoulder within 22 months. last surgery was 12 weeks ago. I am not where I need to be in PT with conditioning and strengthing excercises, so my surgeon prescribed a liquid Dexamethasone 120 mg/30m for my PT therapist to use on me with ultrasound beginning next Tuesday.. I have lots of inflammation and pain in this area. I take warfarin for stroke prevention. is there an adverse reaction to having this injectiable dexamethasone into my shoulder while taking warfarin?

I DID NOT KNOW THIS WAS A PAY FOR AN ANSWER. PLEASE FORGET THE QUESTION. THANK YOU.
