The non-medicated patch provides up to eight hours of low-level heat, which targets pain in the back and muscles, GSK said.

It works by “increasing blood flow to relax stiff muscles, reducing muscle spasms, and delivering the body’s natural pain relievers”, the manufacturer said.

Voltarol brand manager Charlotte Perry said the new addition to their topical pain relief options offers patients "even more choice".

“Pharmacists continue to play a crucial role in advising body pain sufferers on treatment,” she continued.

Voltarol Heat Patch retails at £5.79.
