Hi!
I am sorry to hear about your son’s medical problems. If the skin blotches are purplish in color then he could be suffering from purpura. The purpura could be due to bleeding blood vessels (secondary to low platelets, low vitamin C or K or due to clotting disorders), cocaine abuse, idiopathic thrombocytic purpura, and Henoch Scholein Purpura (less likely because of his age).
If the blotches are small then they can be petechiae. They can result from autoimmune disorders, such as lupus or rheumatoid arthritis, bone marrow disorders such as leukemia, inflammation of the veins, as a side effect of certain medications.
Another possibility is a bruise caused by drug hypodermic syringes. Usually these blotches are present on areas of skin easily accessible by the hand.
Most of the conditions mentioned above can also cause fatigue, joint pains, weakness etc. So, all these factors need to be discussed with his treating doctors. Your son needs to undergo some investigations to find out the cause of his symptoms. Also, idiopathic thrombocytic purpura, and Henoch Scholein Purpura can cause swollen lymph nodes and inflammation of blood vessels.
Another possibility is a vasculitis like panarteritis nodosa. This is diagnosed if three of the 11 signs and symptoms are present such as weight loss, nerve involvement, muscle involvement, skin discoloration (blotches), kidney involvement, high blood pressure, positive Hepatitis B or C virus etc. Another possibility is Wegener granulomatosis (antiportease 3 antibodies are also positive apart from elevated ESR, CRP and positive pANCA). Microscopic panarteritis is another possibility is microscopic panarteritis, diagnosed by positive antiportease 3 antibodies, anti myeloperoxidase antibodies, and complements. Hence, a comprehensive test panel has to be done incorporating this.
I would suggest you take a second opinion and discuss all these possibilities with his treating doctor. Hope your son gets well soon! Good Luck and take care!
The eye could be swollen and blurry due to infection, vasculitis, injury, autoimmune disease, dryness or due to raised pressure in the eye. This needs to be examined by an eye specialist.
His first symptons were dizziness and trouble breathing upon even minor exertions How does that fit in to your comments
Thanks
A diagnosis cannot be made on just the first presenting symptoms. The conditions mentioned in the previous posts should be looked into. Your son also needs basic tests like tests for anemia, COPD, fluctuating BP, arrythmia, hypoglycemia etc to rule out these as cause of dizziness and breathing trouble. Ear problems, pinched nerves in the neck and heart related causes like prolapsed valves should be looked into. However other conditions like skin blotches, swollen glands etc cannot be explained by these conditions.
It is very difficult to fit a diagnosis on net. We can only provide you with the possibilities based on the information we have. Until and unless a detailed investigation is carried out, nothing can be said for sure.
