Ok, I m 23 and this is really getting me down. Here is my list of problems, it s driving me mad. I have had all of these on and off for months now and haven t really had much help from the doctors. - sciatic nerve pain in my right leg - sciatic type pain that travels upward through my abdomen - hot flushes in my left foot - numbness in both thumbs - stabbing pain in some joints - a resting heart rate sometimes of 120 - heart palpitations - sensation of cold water dripping on my legs while I m walking - muscle twitches - tinnitus - dizziness - other sensations in my face or limbs that just don t quite feel right (tingling, pain, numbness, hot or cold) I also went to A&E a few months back because of a very severe pain in my abdomen. I had blood tests (which revealed a higher than usual white cell count, and blood and proteins in my urine) but a normal liver and kidney function. I also had an ultrasound done of my aorta etc which showed nothing really despite the fact the doctor heard a whooshing sound in my abdomen with his stethoscope.
