Well, joint pains with rash can be seen in SLE, psoriatic arthritis, fibromyalgia, polymayalgia rheumatica and chronic fatigue syndrome. Gout, though typically affects the great toe, can cause multiple joint pain with rash. Hashimotos Thyroiditis is another possibility. Hayfever and rheumatoid arthritis too should also be ruled out. Crohn’s disease is another possibility.
Another possibility is reactive arthritis, which could have occurred in reaction to something—in this case rash. In this case you need to rule out the cause for the hives or urticaria. Urticaria is usually triggered by allergens, such as drugs, foods, insect bites, inhaled substances, in response to sunlight, cold, heat, stress, exercise, or a viral infection. Other common allergens are pollen, mold, dust, pet dander, or cosmetics. Food allergies like to gluten and alcohol too should be looked into.You may need to consult an allergy specialist.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral. Take care!
Have they looked at your gall bladder specifically?
The reason I ask is because the gas pain that you describe sounds like biliary colic, which causes pain like a steady gripping or gnawing pain in the upper right abdomen near the rib cage, which can be severe and can radiate to the upper back. Some patients with biliary colic experience the pain behind the breast bone. This is typical in gall bladder inflammation.... this symptom is usually less frequent than weekly and the return of the symptom can even be years apart.
Excessive gas links in with the above symptom.
Yellowing/pale stools - also a symptom in gall bladder stones, bile duct blockage etc.
So this symptoms could be something like cholecystitis.... not sure about the rash and joint pain... however, there is a possibility that a problem with your gall bladder, could cause another problem which may cause you to present with other symptoms.
I'm not an expert, thats just how I have read into the symptoms you have described...
I Hope this information is helpful, Dee.
