For about 5 weeks I have been experiencing the following symptoms: a sense of heat (hot flash-like?) and burning sensations in throat and upper esophagus, as well as externally on skin in upper back, chest and face; tingling of lips and tongue with slight burning, which sometimes includes the nose and/or area between it and lips; resurgence of geographic tongue with burning sores, or ulcerations, but some improvement recently (this particular condition has been going on and off for many years); initially brief sneezing bouts with yellow mucus early in the morning upon getting out of bed, now less frequent and with clear mucus; very mild asthma; fever-like symptoms but no fever; chills at other times; itching in different parts of body; the symptoms wax and wain, some days I initially feel better, and suddenly at some point the symptoms become more pronounced; I have had contact with raccoons but have not been scratched or bitten; I also experience regular contact with grass and other plants because of necessary yard work (mainly mowing); taking sertraline since first week of June and have reduced dosage from 100 mg. to 25 mg. because of side effects, such as increased sweating, and probably feeling hotter independent of other condition causing above symptoms; my mother is having the same or very similar symptoms, so I no longer think the sertraline is fully to blame, if at all; I have also considered a reaction to mosquito control fumigation by the county, or perhaps a fungal infection because of fungus contamination somewhere in the house, as well as something diet-related, as the cause. I do suffer from seasonal allergies, usually in the spring, and from acid reflux (slight hiatal hernia present). I also suffer from insomnia (worsened by the higher-dose sertraline). If this is simply a viral infection, can the symptoms last as long as they have and, for the most part, not cause the usual malaise? I do not think it s the Zika Virus.
