I have a twitch in my left calf muscle and my eye lid. could this be Lou Gehrig's disease? I am 25?

It can be lots of things. I would seriously doubt ALS right off the bat. Irritated nerves, muscle cramps, even thyroid disorders can cause this. Don't get too worked up but see a doctor soon.

Almost certainly .... Look here ---> http://www.alsa.org/als/symptoms.cfm

Depends on how long the twitching has been going on, and there are other symptoms. If you think you have ALS, see a doctor asap, there are ways to slow the progression of the disease.

On the other hand, people get twitches all the time and they mean nothing. So don't get all balled up. If you are that concerned, go to your doctor.

I also have this. A muscle in my leg will twitch every now and then, and so will my right eyelid. I'm not sure what it is. I wouldn't worry about it too much though.

its probably nothing

I have had a twitch in my eye for about a month now, went to the docs the other day and he said its due to stress. Try the quacks

Motor neuron disease, sometimes called Lou Gehrig's disease, is degenerative and affects motor neurons in the brain.

The intellect, eye motion, and bladder control are not affected.

Initial symptoms are difficulty in swallowing or talking; in other cases it originates in the spinal cord, causing initial symptoms such as weakness in the extremities.

About 10% of cases are hereditary and it usually develops after age 40; more men are affected than women.

Lack of sleep and stress can cause eye twitching, other muscular twitches / spasms are generally the result of pressure applied due to sitting incorrectly, sleeping in a funny position or sports.

Could be ...or something else.

Sash.

Unlikely - we all get muscle twitches from time to time due to lack of salt or potassium in our diets, lack of sleep and over exercise.

However if the symptoms persist despite eating a balance diet and you notice a wasting of the leg then go to your doctor for tests.
