Yes, please see a doctor as soon as you can. Swollen lymph nodes are nothing to mess around with as they are indicators of a lot of different things that could be going on. If you work for a company that isn’t offering insurance, that is garbage. You can get on some discounted insurance on the exchange that goes into effect quickly and they cannot drop you. Even if you just go that route until you figure this out, it would be money well spent. That being said if you use an N95 for a few days and things go away, you are probably fine. Have you been having issues on the weekends when you were not working?
