<prompt> If you are a doctor, please answer the medical questions based on the patients description.I suffer from dizzy spells which are exacerbated by me being over warm. While having the dizzy spell my arms feel heavy I struggle to raise them, my eyes ache the light hurts them. I feel as though I am about to pass out my speech is slurred. Many of these incidents happen when I am travelling by bus, car or train most of them happen while I am sitting down. I have only actually passed out on 3 occasions yet I have at least 3 dizzy spells per day sometimes as many as 18. I am also extremely tired all the time very irritable. PLease can you give me an idea as to why this happening? My GP has said I am just one of these people this happens to. I also have high blood pressure which is controlled by 3 tablets I am being monitored as my last 2 ecg s showed a rapid irregular heartbeat .  <response>: Hi, Thank you for posting your query. Your symptoms require further evaluation to establish the diagnosis. Possibilities include presyncopesyncope, vertiginous epilepsy, and migraines vertigo. Investigations would involve a Holder monitoring with cardiac electrophysiologist consultation, MRI brain-epilepsy protocol and EEG. With proper diagnosis and treatment, you would get better. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly
