I have Hashimoto's Hypothyroidism. I get swelling on my right index finger knuckle occasionally which is very painful.
I get this swelling overnight and it starts paining bad during night itself. Today, when I woke up, the swelling was so bad that I could not bend my index finger at all due to swelling in the knuckle. Also, I see some redness on my index knuckle which I think is due to the swelling.
By occasionally, I mean once in a month or so. But, this time, it got pretty bad.
I also have Hashimoto's and experience this problem. I would wake up with the middle knuckle on my left swollen and stiff and hurting. This would last a couple days and happen about once a month. This began two years ago. It has now progessed to being constantly swollen and stiff. It's just a matter of how badly it is that day. Some days its only swollen with no pain, other days I can't even move my finger without great pain. Ibprofin usually helps to gain a little bit of mobility, but thats it. I went to the doctor about a year ago and he did x-rays and ran all my blood work (testing for RA and Lymes) and everything came back perfectly fine. My TSH levels have always been in the normal range since I began medication. If anyone has any information on this, it would be greatly appreciated!!
Sorry I couldn't help you health_conscious, but it's nice to know I'm not the only one this is happening too.
