A lot of what you described are the same things I experience from having Whipples disease sounds like it has spread systemically and to your nervous system. You may want to consider getting tested and checked for it. It's not all in your head I went through the same thing doctor after doctor no one could figure it out eventually I did based off of the health supplement I took. It's a horrible infection that will continue to get worse if not detected and diagnosed properly. Mention this to your doctor if he/she is a good one they will further look into it and investigate it.
