Hi doctor, 2 1and 1/2 years ago I got injured at work nera my neck and upper extremeties. After many, many trials of meds I had turned to Gabapentin, which had side effects of dry mouth and severe weight gain 30 pounds. Decided to switch to Lyrica. Lyrica wasn t any better, actually worse because my feet and laegs swelled up and it was extremely painful to walk. We are trying to wean me off of Lyrica, while weaning me back onto Gabapentin. Here s the problem- while the first time with the swelling doctor prescribed Furosemide 20mg. /once a day. It worked perfectly, as I lost 15 lbs in 2 days, and started to look normal again. Now the swelling has returned and this tim Furosemide not working at all. Feet and legs still swollen, hurts to walk, no weight loss even though I am urinating 2-4 times an hour. I don t know what s going on this time. I am taking meds, but I was taking the same meds before when the Furosemide worked the first time. What could it be, and what can I do that might help the Furosemide to be more aggressive on this swelling I have?

Hello, Well, lyrics and gabapentin are from almost same class. You should increase dose of furosemide to 40 mg once a day, and you should restrict fluid intake(water+tea+ juices +any other Chat Doctor.  Meanwhile, you should investigate for other causes of edema feet, like a TSH, Albumin levels, and an Echocardiogram and renal function tests. Hope I have answered your query. Let me know if I can assist you further.
