Nervous about illness?


Extra details- 15 years old 6ft1 and 185 lbs.

About 2 weeks ago my right foot felt hot, then it went back to normal, and got hot again and went back and forth. It started to worry me. The next morning the hot feeling was gone but the foot and areas of my calf felt odd and a little tingly. Since then, i’ve had all sorts of things going on with it. My foot and calf have been feeling abnormal since then and my foot sometimes gets hot again like on the first night. I would have some occasional muscle spasms too near my left knee and in my right calf, though i was thinking this might be from fatigue. As of a few days ago, i’ve been having occasional burning sensations around my body too, which i’m not sure is related to the leg or if it is just mental. This all has me very worried.

As of a few days ago my right arm has felt a tiny, tiny bit tingly too, but if this is mental or real i don’t know. All i know is all of this has me very worried.

I did some research on the matter and came up with a few things. I thought it could be a vitamin D deficiency since i rarely get any sunlight anymore. I thought it could be multiple sclerosis as well, which makes me nervous. I thought it could also be a pinched nerve in my back, since i sit a lot and have bad posture. Since i came up with that conclusion i have been sitting with better posture, and it SEEMS to be a little better. But would this explain the arm tingling?

I find myself constantly thinking about it. I went to the doctor the other day and only told him about the leg symptoms. I didn’t mention the rare burning sensation around my body or my back pain, and the doctor sent me off saying to wait it out and that it’s probably nothing. When i was there he felt around my foot and ruled out any circulation issues, muscle weakness issues, and i seem to be feeling touch fine in the leg. Now i feel guilty and even more nervous because i didn’t tell him everything, and it just worries me more. He said it was most likely a neurological problem and it COULD be MS. I am afraid because i didn’t mention the other symptoms it could be MS that wasn’t diagnosed. He also asked me if i had joint pain, which i don’t. He proposed it could also be early stages of restless leg syndrome, which wouldn’t explain the other problems.

I was hoping it was a pinched nerve, but the pain in my lower back is more of a dull achey feeling which i think is from sitting a lot, it isn’t extremely painful or anything.

None of this seems to have affected my movement, as there is no real pain.

All of this has left me very worried, the extra burning sensations around my body (though i still don’t know if they are "real" or not) combined with diarrhea has left me nervous. Or could it be that the nervousness is causing the diarrhea? In either case, I had read that diarrhea was a symptom of MS, which makes me even more nervous.

For the past few days, i’ve had less tingling and more of the burning sensation around my foot and calf. This same burning appears to be affecting other parts of my body inconsistently, and i can’t tell if i should worry about it or not. It all has me nervous

I spend hours and hours on my computer and stay up all night often until the sun comes up. I have bad posture along with this and possible vitamin d deficiency because i don’t get any sunlight?

Should i get another appointment with the doctor and say all of this? Is it all mental? Will it go away with time? What can I do? I feel nervous that something bad is going to happen with me. Am i a hypochondriac? I think i’m afraid of having MS, but it’s hard to tell, i just feel nervous a lot of the time. How can i get over this? I’m scared and need help with all of this.

Thought i might add that i haven’t been going out places with friends lately. Should i do this to keep my mind occupied? I’m just tired of all this nervousness and need help
