Postherpetic neuralgia

This study tests whether dexamethasone palmitate, a steroid, can better relieve shingles pain and prevent long-term nerve pain compared to standard care. About 954 adults with shingles rash and severe pain will receive the drug by injection or infusion. Researchers will track pai…

This early study tests a brain stimulation device for people with long-term nerve pain that hasn't responded to other treatments. The device is surgically placed to send mild electrical pulses to specific brain areas. The main goal is to see if the procedure is feasible and accep…

This study tests a lidocaine spray (APC101) for people with postherpetic neuralgia, a painful nerve condition after shingles. The spray delivers pain relief without touching the sensitive skin. About 333 adults will use the spray or a placebo to see if it reduces pain over 24 hou…

This study tests a special gel applied to the skin to see if it can quickly reduce pain from shingles. Thirty adults with shingles-related pain will receive a single application of the gel. Researchers will measure pain levels before and after application, focusing on relief with…

This study tests whether a non-invasive brain stimulation device can reduce the persistent nerve pain that sometimes follows a shingles infection. Researchers will compare real stimulation to a sham (fake) procedure in 94 adults who have had pain for at least 3 months. Participan…

This study compares two types of pulsed radiofrequency treatments for postherpetic neuralgia, the long-lasting nerve pain that can follow a shingles infection. One hundred adults whose pain has not responded to standard care will receive either the regular or a new 'STP' irregula…
