You may experience knee or foot pain without remembering that you have injured it. Well, it might be coming from the joint above or below!
Our body is connected in a way that one joint may have an effect on the other if dysfunction arises and joints are not moving properly as it should.
Here is a scenario, you have a muscle spasm in your low back and you are leaning towards one side when you walk. What that ultimately does is putting more weight on one knee when you limp.
Now, muscles adapt to new movements fairly quickly. A week of limping may be enough to allow the knee muscles to work differently and puts different pressure onto the knee joint itself. As time goes by long after your back spasm recovers, you may notice that you get the occasional knee soreness and that might be because your joints and muscles are just used to move in the improper way.
Conversely, if you have a history of multiple ankle injuries and the ligaments are weaker, this may affect the way you walk and in turn, affect your pelvic alignment!
Whatever it is, having a check-up from a qualified chiropractor can help you understand your biomechanics better and improve your overall function sooner.
Plantar fasciitis is a common foot complaint that affects a persons heel. Symptoms involve a stabbing pain/stiffness at the heel or sole of the foot. Pain is generally worse first thing in the morning and after exercise but not during it. Pain can also be triggered by long periods of standing or getting up from long periods of sitting
Plantar fasciitis is a condition in which the plantar fascia is affected. The plantar fascia is a connective tissue that runs under the foot and serves the purpose of supporting the arch and acting as a shock absorber to weight bearing activities
Plantar fasciitis occurs due to overload on the tissue, leading to degeneration and subsequent pain. 
Those at greatest risk are individuals over the age of 40, athletic individuals [particularly runners], obese/overweight individuals and those with structural foot issues [flat feet/high arches’]
Treatment involves rest, ice, load management, medications and physical therapy. Physical therapy will primarily look at strengthening up the intrinsic and extrinsic muscles of the feet and lower leg. Insoles may also help however surgery is rarely required and often a last resort
Here are some exercises that may help speed up your recovery process
Heel raise [Toes dorsiflexed]
Towel toe curls
Plantar Fascia stretch
Remember to consult a health care professional before commencing these exercises
