Recommendation for Active 74yo with Sciatica?

My mother is visiting from Texas to care for my son for the next 2 weeks.  She is VERY active and healthy, plays tennis 3x per week, and walks daily.  Unfortunately, she recently developed debilitating sciatica, and is unable to sleep or move well.  She has tried chiropractic care, physical therapy, and has been prescribed drugs from her GP but nothing has worked.  She has had an MRI but can't get in to see a pain management doc in Texas for another month.  Is there anyone local I can have her see while she's here to help with her pain?
