It is reassuring that your blood tests are normal, ruling out conditions like gout or classic rheumatoid arthritis. Your joint pain could stem from early osteoarthritis, a post-viral response, or fibromyalgia. For temporary relief, over-the-counter pain relievers like paracetamol or generic ibuprofen can help, provided you have no kidney or stomach issues. Applying warm compresses and resting your joints can also ease the discomfort. Since a proper diagnosis requires physical evaluation, I highly recommend consulting a physician or rheumatologist to determine the exact cause and discuss a safe, long-term treatment plan.
