Tingling extremities are quite common during ssri withdrawal.
If you had diabetes then you would have more noticeable along with this, such as the thirst for sure, and you would be craving sweet foods most likely. A lot of people also feel an odd sensation when they urinate due to the sugar level.
I also have this patch of dry skin on my neck. I couldn't sleep well last night due to the tingly feet and the worry. I'm going to call the doctor today to see if because of this symptom I can get an earlier appointment. I don't think I can last a month worrying that I have diabetes.
I am never this anxious about my health and in fact am always rather cavalier about it. Haven't taken care of myself for years and am so afraid I've let my body go to waste. I have never told anyone this (am going to go to a therapist next week and "fess up") but nearly four years ago I made a suicide attempt.
I'd been having trouble sleeping and was depressed due to circumstances in my life. Didn't want to live anymore, but I was also so afraid of hurting my family. I eventually got sick of thinking about suicide and doing nothing. So I took some of the sleeping pills my psychiatrist prescribed (I still feel so guilty for never telling psychiatrist and for violating trust. It makes me feel f**ked up.) I washed them down with wine. I didn't die and never went to the hospital. Convulsed a little and had very blurry vision, as well as feeling very drowsy. My memory of all the details is hazy. Since then my urine has been somewhat cloudy. No other symptoms in nearly four years.
Now I'm getting healthy physically and mentally at last. All the worry about telling someone, confronting what I did, as well as extreme worry I've destroyed my health due to that attempt and other lifestyle choices is making me crazy. These tingling feet are only exacerbating my anxiety.
