More than 1 yr has lapsed since diagnosis of TNBC stage 1 and grade 3.My wife completed all the treatment as per oncologists advice(surgery,chemo ,radiation).Last radiation received in Nov 2017 end.
She has been doing well except some shoulder problem and mild lymphedema.But yesterday in middle of night she woke up with pain in upper chest ,throat and back.As she tried to drink water, pain was more especially with swallowing movement and she felt something sticking in chest while swallowing.Pain stopped after some time but some sticking sensation still remains.What could be cause and till what time I should wait for symptom to go ,before going for expert opinion?
