Could Swelling Of Eyelids Along With Redness Be Due To Lithium Carbonate?

Hi, I have been taking 450mg of lithium carbonate SR and 60mg of cymbalta per day. Recently I felt that the medication was doing me more harm than good so I stopped taking the lithium then a couple of days later I ran out of cymbalta. Realising this was a mistake I started back on both medications and now approximately once a week over the past 3 week I have woken up with swelling of the eyelids, redness above and under the eyes and on the cheeks. Could this be related to starting back on the medication.

Thanks
Lyndell
