Tecfidera and constant respiratory infection

Good morning, Anyone on tec find they had a constant cough/wheeze/bubble in their chest? I think this is the 3rd time since the start of March and with only a few weeks of having no symptoms. I was never really ill before tec and was aware of the risk of immunosuppression but this is taking the p*ss 🤣 I'm a teacher but did do a bit of research of people taking tec and working in schools and hospitals before deciding on the medication. My Dr won't actually see me to listen to my chest but have had bloods and swabs taken and it's not a bacterial infection, apparently a series of viruses but surely not all this close together Any experience or advice greatly appreciated!
