<s>[INST] Hi,im having a weird feeling in my upper abdomen just below the rib cage,its almost a tickle feeling or crawling,i do have some kind of cold or sinus infection ,where i feel kind of dizzy and my head is heavy,but ive never had this feeling before,its about to drive me crazy,its also like a full feeling,hard to explain,please help [/INST] Hi Thanks for askingBased on your query my opinion is1. Sinus infection and the tingling sensation are not related.2. Abdominal fullness or discomfort may be due to gastritis.3. Tingling/ tickling sensation might be due to vitamin deficiency or just a local skin reaction.4. If there is pain or mass in the rib cage or inability to move then it's of concern. It needs to be evaluated.5. Take multivitamin supplements along with anti-inflammatory agents and antibiotics for sinus infection. Hope this helpsRegards </s>
