What causes the inability to move the arm?

Posted on Fri, 18 May 2018 in Brain and Spine
Question: I have been awake and moving for over an hour and my left hand is "asleep", pins and needles thing, which is normal when you sleep on a limb hard and don't move, but it has been over an hour and still feels that way, this can't be normal. and I have to go work a 12 hour shift at noon. I can't have my left arm and hand not working..... I have ptsd but the only med I am currently on is prazosin for my high blood pressure and to help with my nightmares. I went off my paxcil 8 days ago because it doesn't help and I don't like being on meds. so am I going to have a stroke at 38? what's wrong that my left arm wont wake up?

Brief Answer:
Left-hand numbness causes

Detailed Answer:
Hi XXXX, thanks for asking from HealthcareMagic.

I can understand your concern. Your left hand is numb for more than 1 hour. It can be due to

- Neuropraxia - Neuropraxia is a type of temporary nerve injury which results from persistent pressure on the nerve for a long duration. It can happen after sleep/bad posture/sleeping on a hard surface. It is a totally reversible condition after pressure is removed. It may take hours to a day.
The main symptoms are tingling/numbness/feeling cold/inability to move limbs and extremities.

- Acute neuropathy due to viral fever/drug toxicity/ischemic/traumatic. It is unlikely in your case.

- Thoracic outlet syndrome - It means compression of either vascular or nerve or both, which supply left side hand. It can be confirmed by examining your pulses in different positions, X-ray chest/MRI shoulder and chest. It can be suspected if rest diagnoses are excluded.

- Stroke - Ischemic or bleeding. It can be suspected of deficit persists and/or worsens. Your age is against it (young). However, if it persists/ worsens, consult ER and neurologist for examination. MRI brain with DWI images may be needed to confirm. It can be completely treated if the duration is less than 4 hours.

I am suspecting neuropraxia in your case. Continue hand movements and avoid any tight clothes. Observe it for 1 more hour, if it worsens, do consult the ER.

Hope it will help. If you have any doubts, do let me know.
Take care.

Brief Answer:
Stroke is ruled out

Detailed Answer:
Hi XXXX, welcome back.

Sorry for the delay. I was busy in operating an emergency trauma case.

You are having sensory symptoms (pins and needles) in your left arm and hand. As there is no weakness, stroke is already ruled out. Don't worry about it. You are stressed because of paresthesias.

You can go to ER to get neurological examination done, if you are very very scared.

But I suggest you can wait. I am keeping possibility of sensory neuropathy/neuropraxia and less likely thoracic outlet syndrome. For relief, you can take

- tablet Pregabaline (usual adult dose is 75 mg twice a day what I prescribe) after prescription.

- take neutron specific vitamin like B12, B6, folic acid, pantothenic acid, pyridoxine, benfotamine for at least 21 days. It will treat any nutritional deficiency.

Wait for routine check up by a neurologist. You can send me your examination and investigations records. I will guide you further.
I am sorry again for the inconvenience.

Hope it will help. Thanks. Take care
