<s>[INST] How serious is heel pain? I started having a sharp pain in my heel yesterday and haven't been able to put weight on it. I have elevated it some. It has been swolen, but I can't think of anything that could have caused it. I am a highschool athlete and getting ready for tryouts in 2 weeks and need to be well! [/INST] hai.in your case it can be due to excessive stress & strain on the heel area.please apply a cold compression two to three times dailythis pain is due to the irritation of the nerve endings.application of crepe bandage will be of good help.if the pain is not reduced please go for painkillers under medical supervision.take care </s>
