Hi .... I am having heavy head in morning when i wake up, my left eye twitches some time, having a feeling like my brain is foggy all day long, i do get some tingling in my head from time to time, i think i also have light/glare sensitivity. I am 35 year old with 220lbs and 5.10 height. I have little high BP 140/95 and was diagnosed for mild sleep apnea. I have been prescribed Norvasc 2.5 Mg. I also feel my mouth is dry and have been drinking a lot of water and my urination has also increased. I am not using CPAP as it does more harm then help. Plus these symptoms got worse sine i started using CPAP and Norvasc ... so want to stop both and see if i see any improvement. When i wake up i also sometime have my left had ring and pinky finger numb .. it goes away even before i get out of bed. Also time to time (not every-time) ... after meals or in crowded places i feel being flushed/anxious. not sure if it s the winter affect .. my fingers and toes feel a lot cold this year. i have no difficulty carrying out day to day functions and also i play rigorous badminton for about 2 hours. the constant brain fog along with vision issues are the most bothersome for me. I did a complete heart test and all came out normal. any advise as what could be causing this? can these be related to norvasc? what next steps i should pursue?
