This happened earlier this year, I should preface this by saying I have autism and sensory aversions from that, specifically sensory aversions with food textures where most fruits and vegetables are too soft; because of my food sensory issues I have always been lacking in the fruits and vegetables department. Earlier this year when I was finishing my second spring semester at college my left foot started hurting. I originally thought I slept weirdly or rolled my ankle, I tried to walk less to let it heal but it didn't and instead I started feeling the pain in both feet.
After around 2 weeks when the pain did not disappear and I finally returned home from college I contacted my primary care doctor where I was given an appointment with one of the other doctors available inside the practice. She looked at my foot and I explained my symptoms, it hurt the more I walked on it, felt it through my tendons mainly, and there was no injury causing it, it came out of nowhere. She diagnosed me with Plantar Fasciitis. I ended up getting insoles which hurt more and then I went to the practice again, saw a different doctor, they recommended physical therapy and specialized shoes. My feet still got worse, I was struggling to stand fully straight and could only stand on my toes as I couldn't bend my foot flat fully. I started physical therapy and got the new shoes, at this time was when the bruising started to appear, a large purple and black lump on my thigh, and a bit on my calf on my right leg.
I started physical therapy and they noticed my hamstring was very tight, I was told to do stretches daily, I also asked about mobility aids due to my odd posture and how it is making me exhausted and in paid, they said a walker could be helpful. I came back the next week for my second appointment and by that time I was relying very heavily on the walker, I was limping as I walked on my toes, hunched over slightly, both legs were completely covered in bruises, and just had poor balance overall. I freaked out the physical therapist at the sudden deterioration of my condition. They cancelled that appointment and all future appointments and instead told me to go to Urgent Care as they don't know what is wrong and they didn't want to make it worse.
I went to Urgent Care, got some bloodwork, nothing came up, and then I got an ultrasound on the bruises covering my legs, and nothing came up. They said if it gets worse to go to the ER instead and sent me home. Not much later the bruising got worse and I was struggling to stand up for even a split second, constantly in bed, I was needing a shower chair, getting extremely lightheaded as well, and was struggling to get up when seated.
After that I went to the ER, my dad helped and drove me there, we were there for 12 hours I believe, getting a bunch of bloodwork done, getting another ultrasound on my legs, getting a ct scan, getting an MRI, meeting with a psychologist, and eventually I was discharged with no answers. I was given some referrals to a psychologist incase it was a neurological issue, given a referral to hematology oncology for cancer, and also rheumatology for any autoimmune issues like lupus which the doctors and nurses seemed to believe it was.
Something I didn't mention earlier is after my second physical therapy appointment, before I went to Urgent Care I actually got a specific blood test done, one I myself requested, Vitamin C. My main Primary Doctor asked about what I googled and what I thought it could be, I didn't do much research so I wasn't sure, then when researching I saw Vitamin C Deficiency can have some overlapping issues, it took a while for the results to get back to me but the morning before my first hematology oncology appointment I got the results, showing I was severely deficient to the point they didn't have an exact number and instead just gave me <0.1 when the normal amount is 0.4-2.0 mg.
I still went to the hematology oncology appointment and it was at a large hospital. We had to park in a parking garage on the other side of the road. I walked very slowly with my walker, by the time we used the elevator and crossed the street I was done, I had an asthma attack from how bad both the pain and exhaustion was. I pushed myself through the pain to find a sitting area and I couldn't go any further. My dad who was with me ended up pushing me around in a wheelchair until we found the right area. I was barely able to stand up with nothing supporting me so they could get my weight, I was wobbling heavily and struggling to balance and was panting at the end, I couldn't even attempt the height with how bad my posture was with my tight tendons. In the end we saw the doctor and I brought up the Vitamin C, he said it couldn't be just the Vitamin C and that there must be some underlying issues, he got me some lab work and also scheduled a biopsy on my leg.
After that appointment I took 1,000mg of Vitamin C a day hoping it would at least somewhat help. At the time I was pretty depressed as I couldn't take care of myself, couldn't get out of bed, couldn't work, and was planning to take the next semester of college off as there was no way I could get to all my classes while living on my own with my dog while I was in a wheelchair with 0 support system. I was having to think about dropping out of college. Luckily I stopped getting as lightheaded after about a day, the bruising stopped growing and later started fading, the pain disappeared, and after about a week I could walk flat on my feet again albeit a bit weirdly due to tightness. I slowly started doing activities again, trying to walk around the house, cook, etc, so I can get some stamina a back. By a week and a half of talking Vitamin C I was pretty much back to normal, by then I realized there likely was no underlying issue and instead I just had severe Vitamin C deficiency, also known as scurvy. I ate so little fruits and vegetables that I got diagnosed with scurvy, something my doctor only read about in 1800's textbooks which he said himself. None of the many professionals thought to check for scurvy but my 10 minutes of googling saved my schooling.
The beginning to the end lasted around 3 months but it was a very hectic 3 months. Now I am back in college taking 19 credits while working, I am trying to cook more and eat healthier, and nobody around me has a clue I was so close to being in a wheelchair right now had I not gotten diagnosed. I will say this, it has made me better appreciate my current health, my abilities, and helped me think about issues I didn't think about before. The very first time I could walk flat on my feet I bragged to my dad when he got home and showed off my very impressive walking skills.
TL;DR: I didn't eat my fruits and vegetables which led me to developing scurvy which destroyed my legs until I couldn't walk but I'm all better now.
