It appears that you are experiencing pain and discomfort from corneal and conjunctival irritations due to possible protein infiltrates or deposits from the contacts. This is the most common cause of such problem due to sleeping in the contacts, in addition to the noxious cornea nerve irritation due to prolonged oxygen deprivation of the cornea. Although then possibility of some cornea infection should be considered, especially if this fails to resolve promptly.
The first step is to remove and discard those set of contacts, as they may contain infection. You need to wear your regular glasses, and not wear contact for at least 3-5 days while you treat the current episode. Before you see your eye doctor, I suggest that you start using anti-inflammatory/allergy over the counter drop (Zaditor) one drop into each 4 times daily. In addition, use preservative free tear drop (refresh Plus) one drop 4 times daily, at separate times from the Zaditor to avoid dilution.
If not resolved significantly by tomorrow, then I suggest that you follow-up with your eye doctor for closer evaluation of the cornea and possibly start you on Lotemax, Alrex or Pred Forte along with a topical antibiotics, such as Vigamox, to clear any infection
