Hello Dr. Andrew , I have be in a large amount of severe joint pain all over that started sudden on this past tuesday afternoon along with nausea, lower back pain, as well as I kept getting pale and my blood pressure was elevated. I have been having salt cravings for the last two weeks to the point where I just want to eat salt. Im also very fatigued all the time and get a little dizzy at times. I also Have notice that I seem confused at times and lose my train of thought more often now. I went to the er and they did pretty much nothing for me, I am concerned about what this could be. I am still haveing all the same symptoms with little to no change. I did have blood work done and MPV and IMM grain was high. Im not sure what that really means. Thank you for your time Terri Thank you for your time.
