Joint, bone, and muscle pain can occur in some people taking imatinib for a long time because the medicine may affect muscles, fluid balance, mineral levels, and connective tissues over time. Fatigue, cramps, stiffness, swelling around the joints, and body aches are also reported by some patients during long-term treatment. Since you have been using Imatinib 400 mg for many years, these symptoms may need proper assessment rather than ignoring them as simple ageing-related pain. Management usually focuses on checking for contributing factors such as calcium or vitamin D deficiency, anaemia, muscle inflammation, electrolyte imbalance, or arthritis. Gentle stretching, physiotherapy, adequate hydration, regular movement, and maintaining protein intake may help reduce stiffness and improve mobility. Doctors may sometimes recommend pain-relieving medicines, calcium or vitamin supplements, or adjustment of supportive treatment depending on test results and symptom severity. Sudden severe swelling, breathing difficulty, chest pain, marked weakness, or worsening bone pain should be evaluated carefully during ongoing cancer treatment.

Boils on the breast are more commonly caused by skin infection, blocked sweat glands, friction, ingrown hair, or inflammation rather than cancer. These boils may appear as painful red lumps filled with pus and can sometimes become warm, swollen, or tender to the touch. They are more likely to happen in people with sweating, diabetes, weak immunity, or repeated skin irritation. Most breast boils improve with warm compresses, keeping the area clean and dry, loose cotton clothing, and avoiding squeezing or scratching the lump. Doctors may advise antibiotic treatment or drainage if the boil becomes large, very painful, or filled with pus. Breast cancer usually does not present as a typical painful boil, but certain breast changes should still be checked properly, especially if the lump does not heal or keeps returning. Consult a doctor if you notice a persistent lump, nipple discharge, skin dimpling, fever, spreading redness, swollen lymph nodes, or a boil that does not improve within several days.
