The symptoms of shingles can generally be divided into two categories. The first involves blisters on the skin, typically unilateral, and the second is that these blisters are often accompanied by pain, which varies in intensity from person to person. Generally speaking, the older the individual, the more severe the pain may be. As for the duration until recovery from shingles, the skin symptoms usually heal within two to three weeks for young people, but for older adults, it generally takes about three to four weeks. If the rash leads to a secondary infection, the recovery may take even longer. This is the duration for the alleviation of skin symptoms. If the condition involves nerve pain, the recovery might take longer. For people over 50, the duration of nerve pain can be significantly longer, and some may experience postherpetic neuralgia, where the skin symptoms have disappeared, but the nerve pain persists, possibly lasting for months or even years.
