✕Common Mistakes
A menudo me tensan los músculos.
Missing the impersonal 'se' makes the sentence sound like you are actively tightening your own muscles, which is not the intended meaning.
A menudo se me tenso los músculos.
Using the adjective 'tenso' instead of the verb 'tensan' changes the grammar; you need a verb to describe the action.

Cultural Tip
In many Spanish‑speaking countries, the construction 'se me + verb' is the go‑to way to talk about involuntary bodily sensations (e.g., 'se me cayó el vaso', 'se me olvidó'). It sounds natural and avoids sounding like you are blaming yourself for the condition. When speaking about health, a relaxed, conversational tone is preferred; you can also add a light comment like '¡Qué molestia!' to keep the exchange friendly.
