Lisinopril and flexibility

Was previously on Micardis HCT; dr. switched to generic Lisinopril HCTZ 12.5 in 11/07 when I went on Medicare & was concerned about cost of Micardis. Since that time I've put on 10 lbs. and had increased pain/muscle fatigue and general lethargy. Unusual, as I've exercised 4-5 days per wk. (incl. aerobics/strength trng/flexibility.) for 20+ yrs. Also, frequently, have problems swallowing pills due to feeling of obstruction in esaphogus tube. In July '08 I awakened to slight numbness/tingling in lips and my lips then proceeded to the swell to the point of pain and my lips (in profile) protruded further than my nose. I received steroid injection and prescription for steroid pack. Diagnosis was possible allergic reaction to new cosmetic product. Today (9/3/08) I woke up with the same symptoms and again had to go to the dr.for a steroid injection & meds. Diagnosis this time (different dr.) was possible side effects of "blood pressure meds." Has anyone else experienced edema of the lips, wt. gain, and problems swallowing?
