Hi, i ve been feeling like there s something stuck on my back tongue and on the left side of my tongue i don t know how to explain it but i feel no pain, every time i eat or even without eating when i swallow i feel like theres something stuck and dry throat or dry mouth, I ve put my finger and i feel like pimples on my tongue i don t know, but it worries me and bothers me a lot, its been like that since about 3 or 4 weeks now. Thank you.
