I have no idea what might be making your finger swell, either. The two may not be related. But it sounds like you need to see a doctor. Most cities have clinics where they bill on a sliding scale, so your fee would be based on your income.
If you are a year out, it's time to get labs done, anyway. Who were you going to have order those for you?
Please note: I AM NOT A DOCTOR. If you want medical advice, talk to your doctor. Whatever I post, there is probably some surgeon or other health care provider somewhere that disagrees with me. If you want to know what your surgeon thinks, then ask him or her. Check out my blog.
Not a doctor or nurse and don't play one on TV...
Low blood sugar: As Kelly asked have you tested your blood glucose level? You didn't say whether you are diabetic (whether in remission or not post-op)? What are you eating? Are you dumping as well? Simple carbs can cause hypoglycemia and/or dumping.
Swelling: Do you have high BP? Pre-op and/or post-op? Still on meds? Diruetic BP meds are usually stopped post-op to help prevent dehydration which may mean you have some swelling at times. Any discoloration of your ring finger? Do you wear a ring while sleeping?
If your blood glucose is normal, the swelling and dizziness could be related. Do you feel dizzy when you stand up from eating? What is your resting heart rate & BP? Too many questions and too many possibilities.
I am type 2 diabetic in remission since my surgery but will become hypoglycemic if I eat too many simple carbs. I don't dump though.
I also have high BP. Post-op my Lasix was discontinued. My resting heart rate dropped as my weight & high BP did. I became dizzy when standing too quickly. Last fall my resting HR was 38 and I was diagnosed with Bifascicular block in my heart conductive system. I was born this way but since I've been obese my entire life I've had an elevated BP which masked the condition. My BP med was cut in half which raised my resting heart rate without raising my BP. I will occasionally get swelling in my hands & feet especially if I've eaten too much sodium.
Bottom line: as Kelly recommended you need to find a no cost/low cost clinic and have this checked out by the professionals. Good luck!
