<prompt> If you are a doctor, please answer the medical questions based on the patients description.I ve been very tired I have Raynaud s and its worse than ever. I m either freezing or sweating. I have a little numbness in fingers and my hands and finger joints are swollen all nightpain. I have experience stabbing pain in right side of neck and groin area. I took a 30 min nap because I could hardly stay awake. I woke up with a bruise on my bottom lip. No pain or swelling. Oh also when I was napping I had some chest pain that has continued for a few hours. But has stopped. I ve had palpitations in the past. What could all of this be?  <response>: Hello, It is necessary performing some tests in order to investigate for the possible causes underlying your complaints:- Thyroid hormone levels for possible thyroid gland dysfunction- Complete blood count, PCR, ESR for inflammation or infection- A chest X-ray study- A urine bacterial culture for infection-Kidney and liver function tests- A cervical spine X-ray study and chest X-ray study- An abdominal ultrasound should discuss with your doctor on the above tests.
