I took several medicines and I have a numbness in my mouth?

Dr. A benzetacil was given at the end of November and together I had a treatment with piroxicam, and I started taking pantogar on December 24 one capsule per day. I wonder if there is any risk? I do not know if it's already paranoia in my head, but I feel that after taking the pantogar I feel my mouth numb (lightly). Ahh, I'm also taking Predisin. Thank you very much, and I'm waiting for the answer.
