Wellbutrin and antidepressents

Has anyone had long term side effects after taking Wellbutrin. I was on ot for two years it helped with my anxiety and energy levels a lot. When the doctor put my dose to 300 mg I had severe muscle pain and swelling in hands, feet, ankles, legs it went down after I went back to 150mg. I tried to up my dose but the same thing happened. After two years of wellbutrin I developed severe headaches feels more like head pressure so I went off wellbutrin. would still have muscle pain and swelling from time to time. started developing severe pain in legs and now everywhere along with muscle twitches and muscle loss. I now am 32 and have severe memory problems and no doctor knows what is going on with me. Has anyone had anything like this or heard of anyone with these problems.
