guinea pig abscesses

Question
I have an 18month old male guinea pig and he keeps getting abscesses usually on his neck or at jaw line.It may be coincidental but he always seems to get an abscess after we have been away on holiday and we have left him with friends (who look after him exceptionally well).Do you have any suggestions to prevent the recurrence of abscesses?We have just returned from 2weeks holiday and he has had another abscess lanced(lots of very thick pus!)Thanking you in anticipation.

Answer
Hi Barbara

It is perfectly possible that the abcesses are caused by the stress of being left with strangers. Guinea pigs are sensitive animals who dont like much change.

As to preventing them from happening in the first place I dont know of a way of doing this.
