Hamstring issues are common but are often poorly diagnosed and treated. They are usually much more complex than ‘ a bit tight’ and need careful assessment and treatment. The whole of the spine, pelvis and lower back as well as the nerve (sciatic) that pass through the hamstring.
Imbalances in the strength between quad and hamstring are common causes of overload. Poor biomechanics and techniques in both running and gym work also present difficulties.
To get a good result, as well as treating the local tissue issues of scarring, healing muscle and local strength, you have to look at all of the above as well.
There is no such thing as a simple hamstring tear!
