Zoloft Side-Effects

Hi, My dad has been on Zoloft for 8-9 years and has just weaned himself off of it. I am wondering if his symptoms are what any one else is/has experienced and may be a result of Zoloft. They started right around the time he started taking it and are still occurring: joint pain, legs feel weak and like cement, shocks in face, tooth pain, teeth feel swollen, electric shocks throughout body, can't sleep, extreme temp sensitivity (showers cannot be more than luke-warm), quick to anger, heightened sensitivity to noise and light, feels like he has the flu every day, low grade headache with sharp pains in the eyes. The more I am researching the more I think it is from Zoloft, Paxil and Prozac use as opposed to what I was thinking could be MS! Thank you!
