Welcome to HCM
We understand your concerns
I went through your problem description. You should ask your friend not too worry too much. The symptoms you provided, even though not exhaustive, might be leading to stress
. Anxiety related to stress always elicit such symptoms. Sweating, chest tightness
, feeling anxious etc should not be seen as problem itself. They could be symptoms related to physical and pathological conditions.
Before concluding the problem as stress related, do consult a physician and seek his advice.
Hope this answers your query. Available for further clarifications.
