Have you addressed these symptoms and concerns with your doctor to find out if these are some possible side effects of one or a combo of the meds?
If it is an allergic reaction from the meds, would you be willing to try non drowsy antihistamines? (there are some cases where individuals using antihistamines became more depressed w/ prolonged use)
If you are open to natural remedies for the swelling, maybe you could consult w/ a naturopath or an herbalist (and always let your physician be aware if you take any supplements since they are not controlled by the FDA in the USA)
Some herbs used for allergies and also are being used for swelling due to hay fever are ( Burdock, Comfrey, Golden Seal, Echinacea)
