Hello Again, Background You've Read Before:54 Yo Female. 35 Years

Question: Hello again, background you've read before:54 yo female. 35 years working as a dental hygienist - very difficult to keep proper posture. Pain started in 90's and been managed with chiro, physio, massage etc. I get heavy arms, right arm can get cold (occasionally) lots of back pain, sometimes muscular, sometimes bones. Pain comes thru chest at times. Wakes me up at night, not good staying on back. MRI: mild multilevel degenerative disc disease. No compression fracture. Incidental not of several vertebral body hemangioma No significant spinal canal stenosis or neural formaminal narrowing. Mild posterior disc osteophyte complex at T5/T6 causes minor impression on the spinal cord anteriorly.

You've answered/explained this above before but since then, I was involved into a multi vehicle accident the Tuesday where we where rear ended HARD at full stop. I didn't hit anything in car, air bag didn't deploy, I was wearing seatbelt. no injuries. I had no pain in neck or back or anywhere. Following 3 days a slight headache which is now completely gone. No neck pain. Today, I started feeling slight tingling at T5-T6 area, no extra pain or other symptoms. I've been icing it today. Am I correct thinking just inflamed from the jerk of the collision?
