I got an ultrasound at emergency room that confirmed the DVT has not returned but the edema was significant and I was concerned it might be a symptom of something serious so I called Dr Maloy and said I needed to come in. He saw me same day and after a few Q&A that revealed I’d been working in the heat almost daily (I’m 68 yrs old) doing some pretty significant manual labor, he diagnosed insufficient electrolytes and sent me to the drug store for some over the counter electrolyte powders and said I’d be fine. I’ve taken a few days off and am drinking 16oz of electrolyte solution every morning and I swear my legs are shrinking back to normal and I feel less fatigue in my extremities. Wasn’t a big deal but I didn’t know that till I saw Dr Maloy and I’m very relieved. He’s a great doc, there when you need him and listens when you need him to. I have lots of confidence in the care and advice he gives. Please share this feedback w Dr Maloy. I’m back on the job today!

After a brief wait the doctor or NP join you and talk about the reason for your visit without making you feel rushed. This must be a great place to work because everyone seems happy to be there. must be a great place to woreveryone seems to be happy. I pass several medical offices on my drive to Sigma
