Transient weakness: Temporary reduced muscle strength and shakiness can follow prolonged overuse of those muscles and this isn't necessarily a serious issue if you don't develop weakness with normal but somewhat strenuous exertion. The difference is the very prolonged muscular overuse often in ways you're not accustomed to. If you have further concerns, consult your physician or a neurologist for evaluation. ...Read more

Both of my arms were numb from the forearm down for two weeks. Now the numbness is gone but they feel weak. Could this be a pinched nerve?

Yes: Forearm numbness down to the hands can be very complex. It will require more detailed explanation of the pattern of numbness/weakness and may be either from your neck , your wrist, or your elbow compressing a nerve. I suggest you see a physician (neurologist or neurosurgeon) asap to get a hands-on study and likely a emg/ncv (a nerve study) to better make a diagnosis. ...Read more

I'm 17 and for a month I'm having a weird pressure like feeling in my heart,  then my left arm started to feel weak and my back started to hurt?

Exam needed: Coronary artery disease would be most unusual at your age, but other heart pathology like valve or heart muscle disease are possibilities. However anxiety is a common cause of these symptoms especially if the symptoms are noticeable at rest but not with exertion. For peace of mind have an examination by your physician and appropriate tests can be ordered. ...Read more

I get random twitches in my shoulders should I be concerned? Plus i feel weak on my right side arm and leg but no loss of strength just worry some.

I get random twitches in my shoulders should I be concerned? Plus i feel weak on my right side arm and leg but no loss of strength just worry some.

Reccomend seeing: Your doctor. This could be nothing, but would need physical exam and thorough history to rule out any issues. Again, this could be nothing but an irritated nerve, with one sided weakness i would want to rule out more serious issues like ms. Not likely that, but just to be cautious, consider having an MRI done. ...Read more

I woke up with intense pain in arm up to shoulder blade and my hand all crippeld up where i can't straighten it feel weak what could this be?

See below: Pain that runs down the arm with or without numbness and tingling sounds like a pinched nerve in the neck. This is usually caused by a protruding disc or bone spur touching one of your spinal nerves as it leaves your neck. This can often improve on it's own with rest and anti-inflammatories, but if your pain lasts greater than one week or gets worse see your physician. ...Read more

I have shortness of breath, a lump under my arm and feel weak and tired and almost faint. Could this be leukemia?

I have shortness of breath, a lump under my arm and feel weak and tired and almost faint. Could this be leukemia?

Anything is possible: You should definitely see your doc about all of these symptoms. A few simple blood tests can determine if you have leukemia. However, given your description of your symptoms it is not possible to say what is wrong. This could, for example, be an abscess under your arm and anxiety causing hyperventilation and weakness and feeling tired. Get checked out. ...Read more

Arms feel numb towards the top not the whole arm and legs feel weak they told me I have back arthritis could this be the cause?

Not the low back: Upper arm numbness can be related to the spine, but at the level of the neck. Nerves exit the spinal canal through small holes. Arthritis in the bones of the neck can cause these holes to become smaller, thus possibly pinching the nerves as they exit. The pattern of numbness around the shoulders is much less common however. Electrodiagnostic testing may be helpful. ...Read more

Why does my left arm feel weak after taking adderall (dextroamphetamine and racemic amphetamine)? Is this a normal side effect?

No, not normal: Not sure why you would have this as a side effect, but it definitely is not one that is common. See your general doctor and arrange for an appt that is in the time period when you have this side effect after taking the adderall (dextroamphetamine and racemic amphetamine). He/she can do an exam and help determine if something needs further study. ...Read more
