a few months ago my mum had 5 small benign tumours removed from her face over 1-2 month period, since then her general health has been bad and normally she is very fit and healty. a few weeks ago she went to the dentist who gave her 3 injections in the gums. since then she can't stop having chronic coughing fits all the time even when she is trying to sleep and it is making her feel very down. the doctor said the coughing is a result of the repeated anesthesia jabs and could last 6-12 months! is this correct in your opinion? can you suggest any remedies for her? i am increasingly worried for her. she is 67yrs 5"2 and 10.5 stone
