I have suffered lots of lower back pain , I have visited a really good osteopath a few times and he has put me right, however he did say that lower back problems can cause problems with hamstrings, ITB, calf , and even cause plantir fascitis(if that is how you spell it).
I have however found that recently I have had lots of problems with most of the above mentioned and at the moment feel a complete wreck.
Any advice out there would be appreciated.
