Shingles (herpes zoster) typically progresses in clear stages: first, the prodrome stage with tingling, burning, or pain on one side of the body before any rash appears; next, the blister stage, where clusters of red bumps turn into fluid-filled blisters; then the crusting stage, where blisters break, dry, and form scabs; and finally the healing stage, where skin gradually fades but may leave temporary discoloration or nerve pain. Visually, each stage follows a pattern of one-sided, band-like rash, unlike other skin conditions. Medical treatment (antivirals like acyclovir) should be started within 72 hours of rash onset to reduce pain, speed healing, and lower the risk of complications like long-term nerve pain.
