About 3 months ago, I took Phentermine 15 mg for about a week. Shortly therafter I noticed my right side of my face was swelling. I have gone to the eye specialist, because I initally only noted the swelling about the lower lid - no problems. I have gone to the ENT - some sinusitus shown on CT scan - not noteworthy. 2weeks of Augmentin for possible Salivary gland infection - no improvement and ENT ruled this out. ENT doesn't think it's TMJ. Went to Neurologist and had MRI of brain, nothing abnormal. Tested for lupus and other imflammatory diseases (folic acid and vitamin b ect.) no findings. I am going to the dermatologist now, no allergies noted on testing. Currently taking Zonolan cream 2 times a day for 3 weeks, on the 3 rd day with no improvement. I have consistent swelling for the last 3 months. It seems to me the swelling is mostly on the right cheek closer to the nose area. Some pain in the area, but it's not really significant. some discomfort at times at different places on my cheek, but I don't know it it's just because of the edema. Phentermine was all I took different. I usually take Allegra or allegra D and fiorcet for headaches, about 3 pills a week, depending. Could the phentermine be causing this, I took it once years ago with no problems. Could it be a reaction, muscular, or nerves. I am at a loss as to what to think or do. No other medical conditions do I have. I am 31 y/o and relatively healthy. Smoke 1/2 pack a day of cigarettes, though. Thank you.
