Hi, I had gone through your question and understand your concerns. You haven t mentioned your age, sex, any medical history like Diabetes,sunburn,eczema, or any nerve injury? As per your information,there could be many possibilities. Most likely it could be a peripheral neuropathy which occurs because of nerves malfunction due to its damage or destruction. Also erytheromalgia can be the reason in which blood vessels, are episodically blocked leading to severe burning pain & skin redness which are commonly triggered by heat, pressure, mild activity, exertion, insomnia or stress. Ice and some medications relieves it. I will suggest you need to see a doctor soon to rule it out. Hope this answers your question.
