Taken Beechams For Cold. Have Pain In Mouth, Teeth Numbness, Pain In Eye. Any Ideas?

hi, i had a cold for a few days now and took some cold relief medicine beechams all in one liquid and benylin 4 flu tablets, the cold has cleared up but i have pain in the left side of my mouth as if my teeth feel numb or something is pressing on the nerves causing a dull but sometimes throbbing pain.
