My father has 68 recently had vision problems and extreme sensitivity to smell, his skin gets hives when over heated, and has lack of energy. He has been tested for everything. Recently he went to an eye specialist and he is requesting a brain scan, mri with contrast. Does this seem likely for a brain tumor? His eye is drooped, at times has double vision, when its hot and humid he over heats, gets the hives and his nose restricts breathing. Every doctor has seen him with the exception of a neurologist, and I have been with him when he went. Originally that thought it was his testosterone levels, then blood pressure due to extreme number and has been at stroke
level but was also ruled out. Has had arteries checked too. Mri is not scheduled yet, but would like information as to what would cause this since he has been to every specialist as I mentioned with exception of neurologist.
