HI
Well come to HCM
I appreciate your concern, the history could be suggestive of 
myalgia, some time this does not have any specific reason for this, you have not mentioned your gender here else I could suggesting something  in accordance with this.
Suggestion:- Certain nonspecific symptoms are very common, it is all depends
                    how you react to this, some time this go way unnoticed if you do 
                    pay much attention toward this.
Treatment :-  I actually advise my all the patients to avoid taking any 
analgesic                      unless this is highly indicative, here you can have Tab                     
Acetaminophen 500 mg as per needed for other symptoms like 
                    breathing difficulty, suffocation, better to avoid the mental 
stress.
Advise   :-     If symptoms does not improved then better to have counseling
                   (self) do some exercise, 
meditation, try to be happy cheer up  
                    be positive, this would be much better than taking any medicine 
                   for no good reason, take care.
