Due To High BP (186/80) Doc Put Me On Lisinopril

Due to high BP (186/80) doc put me on Lisinopril 10 mg. Didn't bring it down much so increased to 20 and now 30. The first day I took 30 my teeth started aching so much I couldn't chew food. This is only the third day on 30 but still aching, laying here with a heating pad just to not cry. I'm pretty sure it isn't due to my usual allergies because nothing that works for pollen has made a difference. Is it possible it is due to the drug?
