Hi there!
It is not abnormal to have an accessory spleen and this is unlikely to be related to your symptoms.
Nausea is a very non-specific symptom and could result from GI infection/ inflammation, micronutrient deficiencies, GI motility issues, o non-GI causes such as stress/ anxiety, hormonal/ endocrine imbalances, metabolic issues, micronutrient deficiencies, medication side effect etc. I would suggest getting this evaluated by an internist initially and depending on the cause diagnosed/ suspected, it can be managed accordingly or specialist care may be sought.
Hope this helps.
Take care!
Hi there,thank you for your advice. I was diagnsed with endometriosis just yesterday and am now recovering from surgery.
