About 4 weeks ago, I started experiencing a burning sensation on my back and chest. It was mainly triggered when clothing (like a sweater) touched my skin, causing discomfort and sensitivity. This lasted for about 2 weeks.
After around 2–3 weeks, I had episodes of night sweats while sleeping, where I felt very hot under covers and cold when uncovered, with difficulty regulating body temperature.
During that period, I also developed persistent itching in both legs.
About 1 week ago, symptoms changed and worsened:
Day 1: Burning sensation returned on back and chest.
Day 2 onwards: The burning became more intense and started spreading from my back to my shoulders and arms.
Over time, it continued to spread to my neck, hands, and now includes my face area (around lips, nose, and eyebrows).
Overall, the symptoms are progressive and involve spreading burning sensations and skin sensitivity.
What could that possibly be?
