I would like know what pronunciation correct that sentence.
"Medication to ache head" ou " Medication to headache" ?
Daniel - my biggest advice to anybody who learn foreign language is: do not translate literally-never! Start thinking in English and then you would use English structures naturally :) good luck!
Forget about your native language when you do speak foreign language ;) specially when it's a different family of languages. For example when you learn Spanish, your native language may be useful, but if it's English forget it please :)
