I Had White Foam Excreting Out Of My Mouth After

I had white foam excreting out of my mouth after taking prescribed Doxycycline when I had a bad infection. I had been taking Calcium with Vitimin D for years and I had an adverse reaction the next day after taking Doxycycline. Not knowing what was causing all the white foam, I continued to take the 2 pills. All that foam I later realized was hydrochloric acid that burned my stomach, esophagus and back of my throat. Couldn't breathe correctly, severe cough--all that happened Aug 4 - 11, 2014. Now I has severe burning sensation in my stomach, esophagus and the back of the throat. Saw a number of Dr. during that time and all said the white foam was was excreting was "nothing ". Now I am suffering the consequences of their diagnosis and a Throat Specialist finally told me the back of my throat has a ton of broken blood vessels. Finally the correct diagnosis, which explains the sharp and severe pain. The violent & uncontrollable cough back Aug 1- 11, 2014 ruptured all the blood vessels in the back of my throat and I kept trying to explain it to all the Dr.'s and nurses at that time, unfortunately no one listened and they thought I was having a heart attack because I could not breathe. How will the throat specialist be able to heal the broken blood vessels in the back of my throat? And will they be able to heal all the damage the hydrochloric acid secreting up my stomach, esophagus and out my mouth for weeks and months that no one took seriously at the time. I never had acid reflux or any heart burn prior to this and they kept telling me that's all it was. I know better, I live in this body and have always taken good care of my eating habits, health, etc. What can I expect re: potential healing, hopefully. I'm tired of living in so much pain since Aug. 2014.
