I'm really worried because after recovering from COVID in May, I've been having chest pain that comes and goes. At first, it eased up but then returned. I had a couple of ECGs; one was normal, but three months later, it showed an irregular heartbeat, although all other tests came back normal. My doctor thinks it might be costochondritis since the pain is really sharp and in the upper rib area. Last night things got intenseI woke up suddenly with really strong palpitations. A doctor I know recommended some medications including Thiospas 4 mg, Tramadol, and Dexa 4 mg for 3 days, to be tapered slowly. I've already taken steroids during my COVID treatment for about 9 days, and I'm really anxious about taking them again. Should I go ahead with this treatment? I need advice quickly.
