<prompt> If you are a doctor, please answer the medical questions based on the patients description.2 days woke up withpounding heart rate,dizziness,ringing in ears,tingle in R hand. VSS 98.2 86 20 13070. Have IDDM,Hypothyroidism,Arthritis,Depression  <response>: Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms may be related to anxiety. The tingling in your right hand may be caused by a pinched nerve during sleeping a mild form or Saturday night palsy. It is usually transitory and recovers spontaneously. But it can be associated with a panic attack in the morning, when you wake up with this feeling. Depression and hypothyroidism are closely related to anxiety. I would recommend consulting with a neurologist and performing a nerve conduction study to exclude possible pinched nerve in your upper limbs. Did you experience other symptoms like difficulty speaking, head spinning etc.? A transitory ischemic attack could also cause this symptomatology. Your past medical history is really concerning and every suspicion shouldnt be underestimated. I recommend performing a Doppler ultrasound of the neck vessels, to examine the blood flow to the brain and some other blood lab tests: - complete blood count- PCR, sedimentation rate inflammation- coagulation tests - fasting glucose-cortisol plasma levels-kidney and liver function tests-blood electrolytes, etc. If all the above-mentioned tests result normal, the main cause of your symptomatology would be just anxiety. Hope to have been helpful! Best wishes,
