Sensation in my Tongue with feeling of drynessof my mouth

[shboul]

I had a throat pain (but not tonsillitis), with very bad taste of mucus. I took a clarithromycinfor (500) for 4-5 days (one tablet per day)  at the 3rd day. At different time during the day, I took also Amoxicillin 500 ( 2-3 per day). after 5 days, I stopped taking medicine and my throat pain started to relieve but the problem is: Numbness or Tingling Sensation in my Tongue with feeling of drynessof my mouth. the tigling has dispeared gradually but still dry feeling in the mouth however saliva is present. I saw doctor, she just gave me mouth wash and tablets for nasal congestion (I don't know why)... I am finishing these tablets today but nothing has changed to the dryness sensation in my mouth. For you help, Thank you
