Hi welcome to Health care magic forum, From the very long illustration of your health condition it appears that there is some thing concerned with the enzymes of the brain, which came out to be out of balance and all these changes will be secondary to these changes.
Though difficult i advise you to consult a psychiatrist
to look after the changes, he is concerned with the changes of enzymes besides the psychological changes. By correcting the imbalance the internal swellings, pains and everything will be corrected automatically, but have full confedence on the doctor. with out confedence no treatment will be successful.
Once this treatment is completed you will find the minor somatic ailments left, which will be corrected by consulting a local doctor, or by otc drugs.
Wishing for a quick recovery and thanks for calling.
