TRPV1 and fibromyalgia: Although the molecular identity of the ASIC3‐, TRPV1‐independent acid sensors is unknown, a possible candidate is ASIC1a, because ASIC1a can mediate anti‐nociceptive signalling in muscle afferents in response to dextrose prolotherapy in the acid‐induced fibromyalgia model (Han et al., 2022).
