If you have strained your THOROCOLUMBAR FASCIA region you are in trouble, this is the major region that holds all the major back muscles together.
Get to see a back specialist today/asap if you can, it is a very hard muscle/group to rest as it supports 90% of your bodies activities.
I would phone MARCUS WEBB, he has some clinics in SCOTTYLAND too, his number is 020 8441 8352.
