In the meantime it is strongly suggested that you make a journal or diary if you will, document the times and days and what you’re doing when it occurs because many times we get to the doctors office and we forget. I would include the camping trip where you went geographically if you went swimming if you drank or swallowed any of the water accidentally even. The least little thing might give the doctor an idea of what’s going on and a direction to look – it may seem insignificant to us and it may very well be the key to unlocking the whole puzzle. If you’ve had any fevers that come and go, anynausea, brain fog – any little thing that might seem insignificant any tiredness any muscle stiffness any joint aches and pains no matter how fleeting, try to write them down and remember when it all started. I live on a farm and I’m a great outdoor enthusiast as is most of my family living in several different states. Many of us have had sudden onset symptoms such as what you described because we are outside and we are exposed to the bites of ticks into the amoeba and bacteria and viruses of unfiltered water. Generally there will be a fever associated with these diseases that one can acquire from enjoying the great outdoors. My brother-in-law who is 6 foot seven and right at 200 pounds the most physically fit man I know and strong as an ox had symptoms like yours only accompanied by a high fever. He had acquired a disease from a tick that the doctors didn’t even recognize they weren’t quite sure what it was it wasn’t Lyme disease they knew what it wasn’t! Still they were able to do an assessment and with treatment it took about a month to six weeks but he’s as right as rain once again. Hang in there! So glad to hear you’re going to make it to the doctor. Please share what you learned and especially any good news about what makes you feel better!
