It sounds like you are experiencing severe delayed onset muscle soreness (DOMS) or a muscle strain from overexertion. To help with the pain and stiffness, you can apply a generic diclofenac gel to the elbows three to four times a day. For oral relief, an over-the-counter anti-inflammatory like ibuprofen or paracetamol can be taken with food, provided you have no contraindications. Keep your arms gently moving within a pain-free range, apply cold compresses, and stay hydrated. If you notice severe swelling, numbness, or dark-colored urine, please consult a doctor in person. Rest from heavy lifting until you fully recover.

It is very possible that your father is experiencing contact dermatitis (an allergic reaction) or a localized skin irritation from Moov spray. Ingredients like methyl salicylate or menthol can sometimes cause adverse skin reactions, including painful blisters, especially if the skin is sensitive or if the area was covered tightly after application. Please stop using the spray immediately and wash the area gently with mild soap and cool water. Avoid popping the blisters to prevent infection. Applying a cool compress can help soothe the pain. I highly recommend having a doctor examine his back to provide the best healing treatment.

Since topical options like Moov spray haven't helped, I highly recommend seeing a doctor or podiatrist. The curling motion when walking can indicate a tendon strain or a joint alignment issue (like a hammertoe) that requires a professional physical evaluation. For temporary relief, you may try applying a generic diclofenac gel to help ease the localized inflammation. In the meantime, please have him wear comfortable, wide-toed shoes to avoid putting extra pressure on the toe.

For additional relief, you can try over-the-counter oral pain relievers like ibuprofen, which helps reduce both pain and inflammation, or paracetamol for pain control, provided you have no contraindications. Along with this, continue the 'RICE' protocol: rest your ankle, apply ice packs for 15 minutes at a time, keep it compressed, and elevate it above heart level. If you find you cannot bear weight or the pain worsens, please see a healthcare professional for an evaluation to ensure there is no fracture.

Wrapping your knee with Moov and Calotropis gigantea leaves has likely caused a severe skin reaction or chemical burn. Please stop using these immediately. Gently wash the area with cool water and mild soap, and avoid popping any sores. You can apply a thin layer of plain petroleum jelly to soothe the skin. Avoid applying any more oils or creams for now. Because Calotropis latex can be very irritating, please have a doctor examine your knee in person to see if a prescription healing cream or generic hydrocortisone is needed.

Since your wife is five months pregnant, please stop using Moov, as some topical creams are not recommended during pregnancy. The safest oral pain reliever for her is paracetamol (acetaminophen), taken only as needed. For drug-free relief, she can apply a warm compress to the area, practice gentle prenatal stretching, and use supportive pillows while resting. Please encourage her to discuss this with her obstetrician to rule out other causes of one-sided back pain and to ensure she gets a safe, personalized evaluation.
