I am in the middle of getting results from a blood test for psoriatic arthritis. Because of symptoms (psoriasis, bad knee, shoulder, neck, back, sausage fingers) my doctor is 99% sure I have it. I am not sure I can cope with it any longer. I'm very depressed. Also I've been some stomach issues, griping and also very dizzy and increased heart rate. Is this something that could be related to psoriatic arthritis? I take a fee ibuprofen a day but I'm reluctant to everyday incase that's what is affecting my stomach. My pain is very bad in the morning and when I've sat down. I don't know what to do. Someone please help me.
