Thank you for your query.
I agree with you that something is wrong with your son and you should seek a second opinion
. The lump in the head and groin need to be examined and investigated thoroughly. These lumps associated with night sweats
, loss of appetite need a detailed clinical and investigative workup:
2. Perihperal smear examination
3. Urine routine
, if required
of brain as you mention of a lump in the occipital area.
I hope I have answered your query to your satisfaction.
Wishing your son an early recovery.
