An ache in the arm that does not go away should be evaluated by a doctor. There are many reasons an arm could ache so it is important to be able to tell the doctor what you have been doing prior to it hurting.
Your arm aches because you might have been sleeping on one arm and putting to much pressure on it. Later, it might feel numb, or might ache. Also, it can happen to both of your arms.
Go see a doctor ASAP.
You are using the muscles too much. Rest them for awhile.
the muscles starts streching every moment you sit down

If antagonistic muscle pairs in your arm, such as the biceps and triceps, contracted simultaneously, it would create a situation where the arm is unable to move effectively. This simultaneous contraction would result in a muscle strain or cramp, as both sets of muscles would be pulling against each other without allowing for coordinated movement. The arm would likely ache due to the conflicting signals and excessive tension in the muscles. Overall, this would hinder normal motions like flexing or extending the elbow.
It sounds as though you may be having trouble with nerves being restricted in your neck. this can be the result of arthritis or some sort of trauma.
A person's right arm may hurt when they are playing the cello because they are moving it back and forth for an extended period of time. A person may feel an ache if they aren't used to playing a lot.
Sleeping with your arms bent can compress nerves in your shoulders or arms, leading to numbness, tingling, or ache in your arm and fingers. This position can restrict blood flow and cause discomfort. Try to sleep with your arms straight to avoid this issue and consider changing your sleep position or using pillows for support.
sounds like Carpal Tunnel Syndrome
Left arm could very easily be a heart attack, that was what I felt along with hot flash and a body tremor. Right arm could be a pinched nerve or strain. If it is your left arm, get to a hospital ASAP. Don't think you can't have a heart attack that you are too young or too healthy or that it just can't happen to you. GO!
