<s>[INST] I have a pain on/in my left heal. It started when I had a long hard day on my feet. Since then it comes and goes. Usually when I stand first thing in the morning it is a sharp pain that after some hours on my feet it dulls somewhat. I initially thought I brused my heal, but it gets no better and thankfully it isn t getting worse. [/INST] In all probability you are having plantar fasciitis of the left foot. That is the reason of your these symptoms. One important treatment is the use of very soft insoles, pressure distributing insole footwear. An example is the sports shoes like Nike, Adidas, and the like. You can get such insole inserts of EVA, Plasticate, Silicon, Boron from special footwear institutes, and please wear these when you are on your feet. Never use hard insole footwear or walk bare foot. The other aspect is to gradually stretch the plantar fascia, which is in a contracted state to is normal length in about 4 weeks, when pain will disappear. There usually three plantar fasciae stretching exercises which can be got from the internet, or a Podiatric surgeon can tell you, should be regularly done morning and evening for 6 to 8 weeks at least. </s>
