Suggest Treatment For Dry Cough And Scratchy Throat

Good Afternoon, I ve been having a dry cough for a few weeks now. Not a cough all day long but spuratic through out the day & night, 5-10 times per day. I ll get a scratchy throat or like a sharp needle like pain in the throat that just lasts a few seconds but makes me cough. I try drinking hot/ warm coffee or tea, & tried drinking ice water also. nothing really seems to help. It feels sensitive towards the back of my right jawbone & to feel under the bone going towards my neck feels slightly swollen or just a little more filled in. I m on a blood pressure medication, I m sorry I don t have the name of it with me. I m on the bp med because the bp has been elevated the last few months, & I have a valve that the dr said was allowing blood to backwash...this being in one of the top quads of the heart. he said the medication should help both the bp & the heart issue. I m also on estrodial & Indomethacin 50mg. I get heartburn quite often have been on Lansoprazole 30mg delayed release but have to be honest, don t take it everyday as I should. thought I would ask for thoughts on this before making a dr appt. I don t feel its post nasel drip. any thoughts or suggestions? thank you so much for your time.
