Given the details you sent in, It seems likely that the âlumps in my throat and chest cavityâ could be swollen lymph nodes. Also, since they are painful when exposed to cold temperature, they are likely to be lymph nodes. Local inflammation due to acid reflux could be the cause.
The treatment is to control the reflux by a combination of drugs and lifestyle changes. For treatment, you would need to consult a specialist or a PCP.
The life style changes you can make are: Avoid heavy meals. Avoid too much of caffeine, tea, fried and spicy food, and drinks both alcoholic and non- alcoholic fuzzy ones. Avoid heavy exercises within 4 hours of a heavy meal. Raise the head end of the bed by pillows to 30 degrees. Go to bed at least 2 hours after eating food. Needless to say, give up smoking.
However a confirmed diagnosis cannot be made on the internet. Yes, your condition requires treatment and if ER is the only option available to you then you will have to exercise that. Otherwise, a PCP can help you out.
Hope this helps. It is difficult to comment beyond this at this stage. Take care!
