I also think I am having an allergic reaction to Zoloft (which I have been taking for about a month in a half, started at 50 mg and then my Doc. uped the does to 100 mg an few weeks ago due to horrifying panic attacks I started having.) As each day goes by my symptoms get worse. My chest hurts, body aches, trouble breathing, stomach pains, constipation, light headed, congested, indigestion, a rash that was on my stomach that put me in the Hospital (which they told me they thought I could be having an allergic reaction and gave me steroids) The Rash went away after the steroids all symptoms went away..then when I went to the Doctor she says I'm not allergic to them because the rash wasn't all over my body and that the rash went away and came back..my gut feeling is telling me my side effects are getting worse and I need to stop and I don't think my Doc. even cares to much about it. I am just scared to stop cold turkey bc of all the horrid side effects..should I stop slowly?
