I have recently ( about 6 weeks now) been put on Karvezide 300mg/12.5mg to lowere my blood pressure, usually 160/95, age 70(female) I also take Lisinopril 20mg, Lipidil145mg,Ezetrol 10mg, Lyrica 75 mg twice daily, and Somac 40mg, as well as Mobic 15 mg. My Blood pressure has dropped dramatically to between 140/74 (highest) to 121/61 (lowest). This has been taken twice a week before getting up out of bed first thing in the morning. However I have been experiencing the following, Dizziness on bending down , and most recently a lot of Arthritic type pain in my ankles, knees and lower legs. This can occur mostly after lying on the couch at night , watching TV, or at bedtime, or even after a walk. I am a very fit 70 year old and partake in either a walk, exercise program , weight bearing class, Age Strong class, 5 out of 7 days per week. I am 170cm tall and weigh 67kgs. The Dizziness worried me initially, ( I have had an attack of Vertigo last year) however this is more Postural dizziness, but it is the aches and pains in my legs that are concerning me most now. My Doctor told me to keep a record for 6 weeks of my blood Pressure, twice a week as directed before rising and to go back to see him then. I suffer from White Coat Syndrome . I am about to do that in the next week or so but would like to have some more information myself prior to this appointment. Hoping you can assist, Thank you.
