<s>[INST] I have heel blisters, that I am trying to let reabsorb, there are white floating objects underneath, what are these? Also, prior to the blisters, I have been having numbness and pain at the back of the heels, it started with a mal fitting pair of sneakers, but that was months ago and I only wore them once. [/INST] Hi I did understand your concern. Your lesion may be a reaction to the new shoes and that can cause such problems. The blisters will slowly heal on their own. You can apply Luke warm fomentation on it with a clean cloth and if they burst apply an antibiotic Chat Doctor. In view of severe pain please consult doctor. Numbness and pain over heel can be due to diabetes, electrolyte imbalance or due to nutritional deficiency or Achilles tendinitis and planter fasciitis would recommend you to get evaluated for these lesions step by step as each have different treatment.I hope this yellowish you all the best thank you for using Chat Doctor. I hope this helps </s>
