I have severe swelling all over my body. Is this normal or am I allergic to it?I am only on 1 MG and have taken it for 4 years. I have severe migranes which caused heightened sensitivities that they thought was shizophrenia. They now realize they misdiagnosed me and found it was the migranes causing my symptoms. Does risperidal make migranes worse and can risperidal cause so ,much swelling and weight gain on that dosage when I hardly eat and exercise everyday. It also gets worse it seems with each passing year. I have gone from a size 2 to a ten. I am currently weaning off the medication and having a lot of breathing problems.
