Hi, I had gone through your question and understand your concerns. You haven t mentioned your partner s age and proper medical history. As per your information, the deposition of sharp acid crystals (uric acid) in joints, often in the big toe is the possibility of the condition called gout, deposits of uric acid (called tophi) which look like lumps under the skin. It affects many joints including elbow.It is one of the most painful forms of arthritis. people who are more likely to have gout if : Have family members with the disease,are a man,are overweight,drink too much alcohol,eat too many foods rich in purines,have had an organ transplant etc. I would recommend you to see a doctor immediately to rule out the condition.Take the medicines your doctor prescribes as directed, tell him about all the medicines and vitamins you take,also plan followup visits with your doctor,maintain a healthy, balanced diet,avoid foods that are high in purines, and drink plenty of water, exercise regularly and maintain a healthy body weight. Ask your doctor about how to lose weight safely.Fast or extreme weight loss can increase uric acid levels in the blood. Hope this answers your question.
