This has not really happened to me before. I was doing heavy landscaping lifting logs and it came on like not just at one and last night it was so tight and the pain in my abdominals was like shooting. But i then took tylenol alive and shower and it went away all night till today and came back today so i believe im throwing something out causing the nerve to make my abdomen feel like bloated or cramps . since it did go away then come back i was wondering jeeze kina feels like someone has an ice pic in my back on and off and that im having cramps in my stomach and my area where my liver is feel like shooting pain . any suggestions.
