12-april-2021 I was covid positive after 14th day I got chest pain visited cardiologist ecg echo done no problem he said due to gastritis again after 10 days visited same cardiologist sob and ecg done problem in ecg found due to stress/anxiety he mentioned etizola beta 0.5 daily once and also gave one dose steroid injection to shoulder and pantoprazole injection to handwhich was around 1000rs. My doubt is how long does steroid injection stay in my body and does it cause any problem to immune system my eosinophilic count is 12% also I have dust allergy.
