Etizolam side effects. Nasal congestion!

I was prescribed with etizolam 0.5 mg for anxiety for 10 days (1 each at night). Initially I felt some symptoms of facial pain and headache.later they reduced i was able to sleep .once I stopped using it I was feeling fast heart beat ,sweating ,sleep disturbance, numbness etc., I was then prescribed with 0.25 mg .but I thought I can wait for 2 days more if I feel well but still I was feeling uncomfortable. So I started using 0.25 mg .I am able to sleep but still feeling headache, facial pain, numbness ,frequent deep breathing . It's been 5 days I started using 0.25 mg  .I don't know how to proceed. PS: I am only using etizolam(0.25) in night and zinc bisgylcinate in morning currently. Wanted to know if I can use otrivin oxy nasal spray along with etizolam as I have nasal congestion Thanks in advance
