i have what I thought to be a sore throat but after about 5-6 days it continued and changed to a Very DRY & irritated throat and SEVERE DRY MOUTH the past 4-5 days. My right gland, just under the jaw, is visibly swollen. I started to drink a lot of water (usually drink almost none) for whatever sickness I thought I was coming down with. About 1-3, 16.9 fl oz a day to start then to 2-3 a day & now much more. I have also had a rapid weight loss of over 10+ pounds in less than a month or less. I am disabled and on medication in which I gained 50 lbs. and have not lost ,or gained, more than a pound or 2 in over 5 years. ( & I ve tried !) It seems like I have a severe sore throat that is hidden behind an even more severe dry throat and dry mouth. It is quite irritated. I was hoping to know what could cause a quite sudden weight loss as well as severe dry throat and dry mouth in which the water only helps for that time, When I drink it, I get an instant gratification but no more and still keep drinking with some hopes of it helping. I am disabled and 99% bedridden and sedentary. I do not get exercise and my eating habits are so bad. I will go all day not eating and then eat a big dinner. It has been explained to me that by doing this, the brain gets used to not getting the nutrients or protein it needs so, the brain goes into a fat storing type of phase. I ve been stuck in this for many years as well as a medication (I previously mentioned) in which weight gain is a symptom. (I have over done my body & its limitations before and have caused pain to myself on this same ride but never for a week!) The day the sore throat & swollen gland was at its worst I did have a hard day. I Drove (too many hours in a truck, in pain & uncomfortable) to the doctor, pharmacy and grocery store ( with help) but the day was hard and long for me and the next day I had full body aches like the flu can be at times, however, almost a week later I still have the full body aches. I do have a lot of medical issues mostly broken bones, surgeries 1 on leg, 1 hip, facial reconstruction and 3 back surgeries and current back issues plus. I don t know if any other issues could be involved but I never had anything like dry mouth, dry throat or rapid weight loss. Any ideas would be great and Thank you so very much for reading this book of a note, just trying to be honest and detailed to get the best answer, but am sorry 4 it :) Thank you so much for your time :) T
