Hi. Not sure if I can be helpful, I had a major flare up/crash about ten days ago which lasted for a good 7 days with a worsening of all symptoms inlcuding horrible dry nasal problems and an odd feeling of pressure around the nose. It did totally disappear after that. My sinuses still feel ab bit drier than usual but nowhere near as bad as before. My facial pain has also lessened from a ten to a three on most days now. I seems that some symptoms do get better. My exhaustion persists though and some other symptoms.
