Swellings 2 weeks after bi-lateral Blepharoplasty for double eyelid

I have just had double eye-lid surgery.  It looked great before the stitches were taken out after 2 weeks - hardly any swelling and barely any bruising.  I slept in big sunglasses - still am 5 weeks on - so my eyes didn't touch the pillow as I sleep on my tummy due to chronic back problems.  There is now a lot of swelling above the stitch line corner to corner on my left eye but on my right eye the swelling is to the outer corner causing a droop of skin which is worse than before the op.  I've been told they are gravity swellings, they don't drain during the day.  I lie down a lot because of my back problems and can't sleep on my back or side.  I'm quite desperate as I had no aftercare instructions but was doing very well - I've used cold compresses, and cucumber, and am seeing my Consultant in 3 weeks but it now looks worse than before the op. and I'm not only despairing but scared too.  Any help would be great.  Also how to moisturise the lids and if I should be trying to massage the *fluid* away?  Thanks for any answers .......I'm in the U.K.
