until you know how lupus is effecting your body......... please do not take anything for granted. I have a major issue with inflammation. what you describe is very similar to what I have on a regular basis. but having said that... it is also very similar to your pleurisy. I have unfortunately seen someone suffer very badly from pleurisy. what you describe is very similar to what they suffered. so until you know exactly how your body handles both pleurisy and lupus, please do not take any second guesses.
When you're stressed, You eat Ice cream, Cake, Chocolate & Sweets. Why? Because stressed spelled backwards is DESSERTS.
