Veins in thighs randomly become visable with tingling and tightness
Hi All, I've never posted here before so I'll try to do the best I can. I'm a 25 y/o female that recently started having panic attacks and severe physical anxiety symptoms. I've been doing better with it and have been feeling better. However, about 6 weeks ago I started having tingling, throbbing and crawling sensations from my ankle all the way up my right leg. I got an MRI and a nerve test done to rule out MS and they both came back normal. I've started exercising a lot more lately to keep my mind busy and dropped from 123 lbs to 115 in the last month (I've still been eating very well I was just very inactive before). I smoke a little (4 cigarettes a day or so) and drink a few times a month. Starting 2 days ago I noticed that on top of the tingling and crawling sensation that there was a tightness feeling in my legs on and off and that I can see the veins in both my thighs randomly. I'll be able to see them for maybe 20 minutes or so and then they'll go back to normal. Could this be caused by the adrenaline from my anxiety? Or am I overreacting to nothing? I've never noticed the veins in my legs before and I find it very strange that they become visible and then not.
I notice the veins in both legs but the sensations only occur in my right leg. Also, would the nerve test have shown if there was an issue with the veins? Please help, I'm dwelling and worried that my worry is making it worse but I want to make sure it's not something dangerous.
Other notes, there is no swelling, no redness, its not tender to the touch. It just feels strange and it's scaring me.
