<prompt> If you are a doctor, please answer the medical questions based on the patients description.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 AE 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.  <response>: Hello, I passed carefully through your question and would explain that it is important for performing further tests in order to investigate the possible causes underlying your complaints: - thyroid hormone levels for thyroid gland dysfunction- vitamin D and vitamin B12 plasma levels for possible deficiency-blood electrolytes for possible imbalance. A brain MRI may be needed. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
