Your symptoms seem to be related to side effects of isoniazid.

I suggest taking antihistamines such as cetirizine to relieve the symptoms.

I also recommend drinking liquids.

If the symptoms continue you should go to the emergency room.

Hope I have answered your query. Let me know if I can assist you further.

Can exposure you cigarette smoke cause a sore throat similar to that of streptococcus? It seems like every time I m around cigarette smoke I get a sore throat, which the doctor has always identified and treated as strep throat. I am wondering if all along it has been a mild form of bronchitis or something similar.

Hello a liitle back story on the past week. I spent time with family and friends this weekend and consumed quite a bit of alcohol. This was Sunday and Monday. Monday night before I went to sleep I burped and stomach acid came up. I didn t throw up, but a little got into my mouth. I instantly grabbed some water, which didn t make the taste go away any. I woke up Tuesday morning and a couple hours later I started getting heart burn and it only increased through out the day. Wed it was still very prevalent. I tried home remedies. Finally a water/baking soda mix finally slowed the action down. I feel like my lower esophagase is still spasiming and bording line ready to give me heart burn again. But my main concern is that there is a lump in my throat right above where my ribs start near the middle of my chest. It hurts to swallow cause it has to pass through that area and there is a pain there. sometimes it just hurts on its own wether it s on it s own or cause I m swalling saliva I m unsure. the pain ranges from 3 - 5 on a scale of 1-10.
