I have seen that some people here suffer from mouth ulcers, nose sores etc. I havent had that problem yet, (touch wood)
How long since you were dx with lupus? and are you taking any new medications that might be causing this? Sorry I'm not much help to you, but I hope someone comes along with more experience to shed more light on this for you.
Hope you feel better soon
I'm sorry your having a rough time right now. With our immune systems suppressed it can take awhile to get over things like the flu, strep throat and viruses. I hope you will call your doctor and let him know about this. You may need another round of antibiotics to get it completely cleared up since you still have some congestion and coughing.
Strep throat was the first problem I had from lupus, but wasn't dx'd yet. I battled with chronic strep throat for a year when I was 19 to 20.
We do however get the sores in the mouth and nose from lupus too. If that is the case there are some good rx's for that problem. Some use the "magic rinse", I think that is what it is called. I use the "swish and swallow", while others use different things for the sores.
