Nitro relaxes and dilates vessels, and very good for angina. But can also be used for esophageal spasms, this pain is often described as a substernal squeezing pain and may occur in association with exercise. Such pain may be indistinguishable from angina pectoris.
Esophageal spasms are often difficult to treat, and controlled studies of treatment methods are lacking. The aim of treatment is to relieve symptoms by decreasing pressure in the lower esophageal sphincter. Nitrates (for example, nitroglycerin placed under the tongue before meals) or calcium channel blockers.
Arthritis has inflammatory characteristics and very little if anything to do with dilated vessels, etc.
