I tested positive for covid 3 weeks ago, I felt quite ill for a few days, mainly tiredness, high temp and sore throat. Tested negative on day 10 and went to develop a dry cough for around 4 days. I feel fine now, all symptoms have gone, but I have developed this pain in my sternum that moves also to the back in between my shoulder blades. It’s very mild when I wake up in the morning ( 2 days ago it went until the evening), but it gets worse in the afternoon and it becomes quite sore. Someone at work today mentioned costochondristis, has anyone had it post covid, does the pain sound similar? The muscle in my back and neck feel really tight too, and the pain at the front is at the top of my sternum going down 3/4 ribs.
