<s>[INST] I am experiencing pain on the bottom of my left foot in the arch area. For the last month or so I have had a knot in my arch and now I am experiencing some pain. The knot is not as large as it was but I feel more pain. I wore some clog type shoes one day this weekend and I felt sharp pain on the top of my foot almost to the point of not being able to walk only momentarily. [/INST] Hello,What I can conclude from the complaints you have mentioned is that you have symptoms of plantar fasciitis? It’s a common condition usually seen after use of improper footwear or excessive strain of the foot ( usually when You suddenly start exercising for ex. jogging and walking). I would suggest you to 1. Wear soft footwear with well-padded heels or MCR footwear. 2. Hot fomentation (dip both your feet in lukewarm water for 10 to 15 min twice) local pain relief gels.  Hope I have answered your query. Let me know if I can assist you further.Regards,  Dr. Santosh S Jeevannavar </s>
