have you also been checked for a underactive thyroid as i get exactly same with my hypothyroidism it is worth a shot..
Hi gibbygabs,
If you haven't already ruled out Candida you might want to check it out. I suffered for years. One of the biggest symptoms is foggy head and poor memory. I went to a dr years before I was diagnosed and they sent me home feeling like I was somehow making up my symptoms. I would be happy to answer any questions but if you Google Candida you will find symptom lists and even tests you can take. Also, Google "Candida Spit Test". It's a simple (gross) test you can do at home for free to see if it is likely that you have Candida. So many Drs don't check for it. I have spoken to so many people who have it and didn't know for years! Hope you find some answers! Blessings! One more thing, Candida also makes allergies worse or in some cases gives you new ones.
Sorry to hear you are still experiencing problems. Did you have tumor removed? Any blood tests? Are you stressed? Have you had any positive changes happen lately? ie: job change, move, marriage, kids?
