What causes my left ankle and foot to swell? I am 54, female, smoke, drink only a little but often (4-5 times a week, usually not more than 3-4 drinks and never more than 6)., and use a small amount of crystal methamphetamine daily by injection. I have used for about 8-9 months. I had a very heavy crack habit until I quit 13 months ago. I am also an opioid addict, and maintain at 25 mg (2.5 mls) of methadose per day, down from 120 mg since July 2013. My weight, blood pressure, cholesterol and liver function have all been normal until now after a weight loss of about 100 pounds which leveled off about a year ago as well.Besides my methadose all I take is an occasional ibuprofen.I have spinal stenosis and Fibromyalgia so I have significant chronic pain.My dental health is very poor. Several of my teeth have broken off and I am currently being treated for abcessed teeth.I m suspecting this is another wonderful symptom of my tweaking habit.What s your professional opinion, and, also in your opinion, if I stop using immediately, what outcome can I reasonably expect, prognoais-wiae?

### output:

Hi, Thanks for your query. There are numerous causes and conditions that produce swelling in the ankle and foot. A few important causes are chronic venous insufficiency, Heart related issues, kidney disorders, liver problems, water retention etc. A thorough and detailed evaluation along with a few investigations are needed to establish the correct diagnosis. I suggest you to consult a General physician for further evaluation and management. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
