I have developed many neurological issues post covid vaccination which I took on 9th october 2021. Within a day I started getting muscle tremors which I initially ignored but it did not go away and I then got sharp poky sensation all around my body. My body felt weak. My hands still shake. It is very evident when I hold my phone or spoon. It is a bit shaky since october. Sometimes the shakes are bad. I have this burning sensation in my left thigh. Sometimes on the right leg too. I spoke to my family doctor and was asked to take b12 tablet which I did take and I felt better for 2-3 days maybe. But within week, nerves pain began and I had to visit a doctor. I was prescribed gabapin and I took it. But the day I took the tablet, my symptoms became worse and I started getting uncontrollable movements that night and couldn't move my right leg for some time. This was back in october. I still have those movements even today. My hands, neck, feet move or fall on its own especially at night and disrupts my sleep. I have an uneasy feeling and pain in my brain, scalp etc. From past 5 months now along with a host of other symptoms. My b12 and vitamin d are currently within range. I later visited a neuro in november as my symptoms didn't go away infact I started getting this crawling sensations too at times along with the rest. After physical examination, he said my nerves seem fine. I did a nerve test too, it was normal. I haven't done an mri of my brain yet. This is still pending. Also he had given me a tablet for my nerves pain but after taking just 1 tablet, my heart rate shot up within 2 hours or so at night and since then it has never gone back to normal. My heart starts beating fast all of a sudden and turns cold, develops chest tightness at times. When it beats fast, my hands also start shaking. This has been constant. It has been 4 months now and my condition has gotten much worse since the heart episode. My cardio reports came back fine but my heart issue remains. Is this nerve related issue causing me heart issues too? Could you please let me know what is going on in my body? Is this curable? Please help me!
