I have had problems in the past with just about everything. I'm 32 years old almost abd I've already gotten my gallbladder removed, ARDS, a blood clot, pancreatitis and Acid reflux. The past few days I have not been able to eat that well without feeling nauseated. I've been real lightheaded. I've had severe back and side pain. I also have IBS and am on a pill called Lomotil but I don't think its my pill causing the pain. When I feel an attack coming in, I get sweaty and I feel as if my heart is going to pound out of my chest. I know its not my ptsd or anxiety causing it. I'm not sure what it would be causing it. Any advice would ve awesome. Thank you.
