I have severe edema in ankles, feet and calves of legs----take Diltiazem ER 60 mg. every 8 hours. I was in ER three days ago--had BP of 221/100---was treated with Nitro gel paks placed over heart and given injection of Lasix via IV and oral potassium. I stayed overnight in ER quarters---by 6 AM, BP was 164/77---edema was only slightly improved---was released with RX of Lasix and liquid potassium. No improvement--significant, i.e.. Something is causing the edema which left in April, after I received via IV Avalox for Pneumonia--did not re- turn until 6 months later. I have infection at root of a tooth---root canal was hurriedly performed and abcess formed/then cellulitis/given Cipro for one month---X-ray still reveals the infection is present at base of root. I will see periodontist next for implant. Is this root infection possibly causing an ongoing infection within my body---causing cellulitis in my legs, causing my BP to soar---usual BP is as low as 140/80 when there are -0- infections within my body ? Please advise re. my situation--would like to remove cause of edema/high BP Can I pay via telephone, using charge card-??--hesitate to enter charge info in computer/was just diagnosed with 60% virus---had removed by Geek Squad ! Please save my question. I plan to call USA Customer Service to see if I can pay by phone- will do on 11-23-2013- is almost midnight on East Coast----Thanks ! Thanks, Esther P.
