Hi There, Since Last Week I Have Had Loss Of

Question : hi there, since last week i have had loss of apetite and nausea and also headaches down the leftside of my head for the last 2 months, a couple of days ago i had a scary experience where i had tingling down the lefside of my face and a bad headache, left side of vision went blurry for a little while and left arm had been aching all day, my mouth was droopy on and off as it would come and go, i went to hospital and they put it down to bells palsy as i still had movement in my arms in legs and could raise my eyebrows. The next day i started experiencing slight pain down leftside of my body. and slightly in my back, my pelvic area also slightly paining and also stomach ehich makes me feel like i need to go to the toilet after i eat, my heart has also been feeling like its constantly beating fast and having shortness of breath even sometimes when i eat something or if i just walk a little bit i have to try catch my breath. i also had ct scan n bloodtest done at the hospital and everything came back normal, my heart rate and blood pressure was good, im ver worried that this could be something serious, i still also need to see the neuroligists and have MRI
