Dear Welcome to HCM We understand your concerns I went through your problem description. I suggest you not to worry too much. The symptoms you are mentioning could surely be due to the stress you are undergoing. You are habitual for the stringent life style for some time, but it is also possible that stress could come anytime. Stress is resultant of so many factors including negative thinking. I meant it is not just physical. Therefore worrying about the tiredness and fatigue and swelling could increase the symptoms you are feeling now. I suggest you to take a break for a fortnight. Get a relaxing vacation, or simply be at home for a week, without thinking about your job. You might need psychological counseling., I am more than happy to provide telephone psychological counseling through healthcaremagic. Contact me through customer care, www.healthcaremagic.com. Hope this answers your query. Available for further clarifications. Good luck.
