<s>[INST] I had an epidural steroid/ cortisone injection for sciatic nerve / back pain this morning - after dinner and glass of white wine - my heart started racing - this has happened in the past but only after running / exercise - my heart rate now is about 135 BPR - any connection with the injection and rapid heart rate - 66 year old white male. [/INST] Respected sirThanks for your query to us.1. Unless you develop allergy to some of the components of steroids injections, tachycardia (increased heart rate) is not likely due to this.2. Wine intake  may be associated with the tachycardia. If you have tried a new brand or you have tried a new combination then it is more likely. Do see your emergency physician if it does not settles down or you have any new troublesome symptom.SincerelySukhvinder </s>
