Internal tremor and legs weakness
I am a 38-year-old man who is quite athletic. I've always been in good health with no major health issues except for an intermittent mechanical problem in my ear since 2014. Mostly my left ear reacts to sounds (both my own and others') and to touch/nearby brushing with a very unpleasant cracking sound. All of this started after an untreated cold and a night full of coughing.
At the end of 2022, I was diagnosed with mild proctitis following some bleeding. There was no pain or false urges. I had a colonoscopy and was prescribed Pentasa suppositories, 1g/day.
At the end of January 2023, I smoked a joint with friends. I felt very strange spasms. Every 15 seconds, a jolt occurred in a part of my body. The next morning, the spasms disappeared but I began to feel internal tremors. I also started feeling tingling in my hands and feet, which intensified if I maintained the same position for a long time.
In February 2023, I felt a pulsing sensation in my lower abdomen, so I consulted a cardiologist: everything was fine.
In April 2023, I saw two neurologists who both believed it to be anxiety. No MRI was prescribed.
From January 2023 to today (November 2023):
The internal tremors are mostly felt upon waking up (whether from a nap or a full night's sleep) and are present in my head and hands. These internal tremors can sometimes be absent.
I've felt weakness in my right hand (when typing) and my right leg (when walking). However, I can still do pull-ups and push-ups without issues.
I've mainly taken dietary supplements (Q10, Vit C, Probiotics, L-glutamine, L-theanine, Devil's claw). The last two seem to reduce the internal tremors, but I need more time to judge.
My fecal calprotectin level is high (1000 at the beginning of 2023, 600 today), and my blood tests are normal.
I'm at a loss and don't know how to diagnose my issue. It's challenging for me to deal with these lingering sensations of weakness, especially since I frequently use my right hand for my job (I work in e-commerce, so I type a lot). After extensive research and consulting various doctors, I'm unsure about my condition. Here are some possibilities: Peripheral neuropathy due to Mesalamine, neurological effects of pancreatitis, functional neurological disorder, cannabis-induced tremors, psychosomatic symptoms related to stress or anxiety, Multiple Sclerosis, and others (including Vitamin B12 deficiency, central nervous system disorders other than MS, circulatory issues).
I would love to hear about your experiences.
