I have a very rare condition from few years which has worse in the last month or so where if I carry any weight my muscle Inflames.
I am 39 years old otherwise healthy with no other conditions.
If I carry groceries bag weighing even about 2 kg on my palms, arms or shoulder or anywhere that part will inflame. It takes days for it to subsided. Anyone knows what it can be? Attached picture are from carrying almost 2kg groceries in a bag on my shoulder for less than 5 mins. Any leads will be helpful.
