Unexplained Leg Swelling and Pain: A Neurological Concern - Neurology

Unexplained swelling and pain in both legs?

---

Hello doctor, on the night of April 27th this year, I injured the bottom of my left foot on a plug, leaving a wound.
I disinfected it and applied ointment, but the next evening, the top of my left foot suddenly swelled up like a hill.
My right foot also swelled, but not as much as the left.
The next morning, I went to the emergency room (although when I woke up, the swelling in both feet had already decreased somewhat).
The doctor administered a tetanus shot and prescribed antibiotics, but as the evening progressed, my feet swelled even more dramatically.
My right foot swelled to nearly the same height as my left, and my ankles were swollen too.
The muscles in the back of my calves felt very tight, and the skin below my knees had a mottled appearance, resembling goosebumps, although my feet were not cold.
The next day, I visited an infectious disease specialist.
The doctor drew blood and reviewed my results, noting that my white blood cell count was elevated due to inflammation, but everything else was normal.
However, she said she didn't know the cause, so she prescribed a stronger antibiotic.
During this time, the swelling in my feet somewhat improved, but every time I walked for an hour, my lower legs would become very red and swollen upon returning home.
Once, I even experienced a tingling sensation.
Additionally, the soles of my feet, possibly the fascia, were very painful, and only elevating my feet and lying down for an hour provided some relief.
However, the skin still appeared mottled and grayish, and it remained stiff.
I subsequently consulted a cardiologist (who performed leg vascular tests but found no cause) and a rheumatologist, who also could not determine the reason for my symptoms.
By this time, it had been two weeks of discomfort.
My symptoms evolved to the point where, although the tops of my feet were not as swollen as before, the front of my feet and toes were now swollen, especially the right foot, which was more severe.
In the evenings, my ankles would also swell, and both my toe joints and ankles would have a dull ache.
Consequently, the doctor prescribed gout medication, emphasizing that I did not have gout.
After a week of taking the medication, I felt that my entire foot, especially the soles, was not as swollen as before.
However, I have not returned for a follow-up and continue taking the gout medication.
Even though I have not been walking outside, the area below my calves remains very stiff and numb, particularly in my right toes, which are still swollen.
The edema in my ankles has not completely resolved after sleeping, and there is a slight ache in the bones between my ankles and calves.
Although the skin color below my calves is mottled and grayish, the color in that area is darker.
Sometimes, my toe joints and the bones in the front of my calves and knees experience mild pain.
After walking a few steps, the tops of my feet feel slightly crampy, and now the muscles in my calves and thighs are also tight.
My knees currently feel noticeably uncomfortable, and I have experienced a few instances where the flesh just above the inner sides of my knees vibrated for a few seconds without pain.
Additionally, for the past two days, my left thumb and index finger, as well as the last two fingers of my right hand, have suddenly felt like they were shocked for a few seconds.
I researched online and wondered if this could be peripheral neuropathy.
I feel that my symptoms initially started as edema, but at that time, there was no pain in the fascia or bones, and it was limited to below the ankles.
However, the discomfort has now extended to my thighs and is painful to the bones.
During this time, I have experienced three instances of cramping in my left calf muscles when I woke up and stretched, which was extremely painful.
I am currently a student who sits at a desk for long periods.
Previously, I would walk for nearly two hours every day.
This year, my diet has included a lot of chocolate and sweets, and I have gained nearly ten kilograms.
Additionally, I have some pain in the bones above my buttocks, and when I sleep, my lower back feels somewhat unsupported.
This has been different from how I felt in the past year.
However, my foot issues began suddenly on April 27th and have not improved, with the affected area expanding.
Despite seeing many specialists, no one has been able to find a cause, and I truly do not know what to do.
I am also very afraid of not finding a reason, which could lead to a worsening condition that might result in disability.
