<human>: my arms from the elbow to my hands get really weak in the last week, and i have tightness of my back shoulder muscles just before this happens. It goes away after about 10 minutes but they are really jello like. It doesn t matter what I m doing when this happens.
<bot>: Hello, Weakness on your arms from the elbow to your hands associated with tightness in your back shoulder muscles could be due to any neurological problem with the spinal cord.  I highly recommend to : - consult with a neurologist and run a good neurological examination- run a good cardiac checkup (EKG, echocardiogram) to rule out heart problems.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
