Hello, Disk bulge may cause nerve root compression at that level may lead to neuropthy pain of hand some times it may lead muscle weakness in hands. Dyspnea and palpitations may be due to other causes like obesity or hypertension or respiratory problems etc. In case of phrenic nerve involvement may also cause dyspnea but unilateral involvement may can cause much problem. So avoid pillows under head. Use soft cervical collor for support. Regular physiotherapy and exercises may be useful. If no improvement please consult with your physician he will examine and treat you accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further.
