Why would it be that my pulse is so high constantly?

Evaluate with doc: High pulse typically occurs in response to physiologic stressors. Some of these can be apparent (pain, anemia, dehydration, excessive thyroid, anxiety), and some can be inapparent (excessive sympathetic tone, arrhythmia, inappropriate sinus tachycardia). An ECG or an event monitor might help along w a doc to review all the data.
