TIA, or other chronic condition?

I was recently hospitalized after a suspected TIA incident. Woke up, was drinking coffee in bed and suddenly had a sinking feeling and noticed my hands/arms felt numb and heavy. Had some slight muscle/spinal pain in back and shoulders and numbness in my face. Started to feel like I was going to pass out and got out of bed to tell my husband. When I got to the bathroom I looked in the mirror and notice facial drooping on right side. I continued to walk toward my husband but when I tried to speak nothing came out but a moan. Within seconds I was able to say “I think I’m having a stroke”, and he ran over to me. I think I began to fall because he wrapped his arms around me and I just leaned on him while he told my daughter to call 911. Almost immediately I had to use the bathroom (defecate). As soon as I could stand on my own, I used the bathroom and then went and sat down. Before the ambulance arrive just a few minutes later, I had to use the bathroom again. EMTs took my vitals and all seemed normal but the suggested I go to the hospital and get checked.
I felt light headed, very weak and nauseous on the ambulance ride and that continued at the hospital. Still some pins and needles as well. I was still having a little trouble getting my words out and noticed that my tinnitus and ear pain was much worse than normal. I also noticed that I had chest pain in one spot next to my left breast.
At the hospital I had a CT, MRI, chest X-ray, ekg, blood pressure, lots of blood work, electrocardiogram and ultrasound of the arteries in my neck. All came back normal.
I was admitted for observation and left the next evening.
Since then Ive had more MRI’s and MRAs, and all sorts of neurological testing. I am also wearing a holter monitor for a week and getting a bubble test looking for a hole in my heart. Testing is taking FOREVER!
I haven’t been able to work since the incident ( 6 weeks ago) because I feel to weak in my legs, and my arms. I feel close to passing out a lot of the time. I get nauseous and I have internal tremors. My ears are ringing like crazy and also hurt. I have tingling in my extremities and have been noticing that my body temp is not well controlled. I will have one warm hand and one cold hand sometimes. My vision is also bad. Blurry and cloudy. Some flashing and spots.
A lot of these symptoms are not new. I’ve been struggling with my health for many years with no answers. It’s just gotten to the point that I can’t ignore it anymore (after seeing dozens of doctors with no help) and giving up. I can’t live my life like this.
The only thing that have been found are a positive ANA test, a high platelet count, high sed rate, high c reactive protein, calcium/iron saturation one point below normal, homozygous MTHFR mutation, some mild disk degeneration and a possible hemangioma on disk T11. I have also been suffering with bad gastritis and diverticulitis. The only meds I took before the initial incident was Nexium for two weeks.
I am probably missing some thing because it’s been a long couple of weeks and so much has happened. I just need to find answers so I can go back to work and not be in total fear all the time that I’m going to just drop dead because I have no idea what’s going on with my body. I hope someone can suggest something that no one has thought of.
