I have a tingling sensation in my hands and feet. Can it be due to anxiety?

Hello doctor,

I am a 26 year old female. At the beginning of this year, I had a bad cold, and two weeks later, I had a tingling in the wrists, feet, and legs, which the doctor said was reactive arthritis which lasted a few weeks. Then, the first time my left hand felt weak was five months back. It felt weak, more so at rest but, when I had to grip things, I was able to. I went to a physio and had a neck massage as my back was also tense and the next day, the weakness was gone. So, the massage helped it. Now, more recently, I had foot weakness on the left side and a weakness and very mild tingling in hand. Again, my back is very tense and tight from gym and work position. As soon as I get this, I get very anxious, and I feel the tingling gets worse. The only difference in daily activities is lifting weights at the gym, weighted squats, and heavier arm exercises. I used the foam roller on my foot last night, and today the foot weakness was gone. The foot weakness lasted 12 hours on and off. There are no problems walking or anything like that. It just felt weaker but, it was not. The weakness always comes randomly but, I do seem to always have a tight back when the weakness occurs as well. Could this be multiple sclerosis (MS)? Does it sound like it? I am extremely worried now. I have never been diagnosed with it. I have just read about it online. What could this be from? I went to the opticians last week, and my eyes were fine. There were no eye symptoms. It was just a standard check-up. My eyes were said to be perfect. I do not have any bladder or bowel symptoms and no other weakness anywhere else.

Thank you doctor,

But, can this be multiple sclerosis (MS)?

Thank you doctor,

Could this just be related to my tense back? So, are you saying that only if I have an actual weakness like not being able to walk, etc., I should be concerned? Could it be peripheral neuropathy?
