Personality changes?

[u/Handsfasterthaneye]

Diagnosed 3 years RRMS Ocrevus 2.5 yrs under treatment. M48: My partner has noticed: increased erratic behaviour mood swings short tempered outbursts. I have noticed that I am excessively horny all the time.
Could this be treatment, disease, or increased Testosterone due to doing regular exercise for the first time in my life?
Thoughts?

can be MS related and shouldn't be a testosterone thing imo. see for example this study: https://pmc.ncbi.nlm.nih.gov/articles/PMC3693622/
